Overview of the NAG1 Transmission

Overview of the NAG1 Transmission - Gearstar Performance Transmissions

Over the course of the years, several transmissions have been launched and one that is worth mentioning is the NAG1 transmission. The NAG1 was quite popular in its time and interestingly, it was used in several Chrysler products.

The high use of this transmission was an attestation of its quality, which made it a force to reckon with. On the other hand, we’ve outlined an overview of the NAG1 transmission and what makes it unique. A closer look is also taken to at cars that used the NAG1 transmission.


What Is the NAG1 Transmission, Exactly?

The acronym NAG1 denotes “New” for N, “Automatic” for A, “Gearbox” for G, and “generation 1” for 1. Also, this 5-speed transmission is used to denote a category of automatic transmissions that have a round 13-way connector.

The connector is stationed near the right side, front corner of the transmission oil pad. The NAG1 can also be called by other names such as the WA580, W5A380, or W5A580. The W5A580 stands for:

    • W = Transmission using a hydraulic torque converter.
    • 5 = 5 forward gears.
    • A = Automatic transmission.
    • 580 = Maximum input torque capacity in Newton meters.

It is worth noting that Chrysler moved to this automatic transmission. The W5A580 / WA580 transmission had several advantages to previous Chrysler automatics, and they were more efficient compared to the four-speed automatics that were evident in the LX-car engines.


Cars That Came With the NAG1 Transmission

The NAG1 automatic transmission was used in several Chrysler products such as the Grand Cherokees, Dodge Caravans, Ram trucks, and Jeep Wranglers. Specifically, some cars that came with the NAG1 transmission are:

    • Jeep Commander (V6 3.7L, from 2006 to 2011).
    • Jeep Grand Cherokee (SRT–8, from 2006 to 2013).
    • Jeep Grand Cherokee Laredo (V6 3.7L 3.6L, from 2006 to 2013).
    • Jeep Grand Cherokee Limited and Overland (V6 3.6L, from 2012 to 2013).
    • Jeep Grand Cherokee (V6 3.0L Diesel, 2007 to 2011).
    • Jeep Wrangler, (gas engines from 2011 to 2014).
    • Dodge Nitro, (V6 4.0L from 2007 to 2011).
    • Dodge Magnum SRT–8, (some SXT, R/T, 2007 to 2011).
    • Dodge Charger SRT 8, (2006-2013).
    • Dodge Challenger, V8, (2009 to 2013 and V6 in 2011).
    • Chrysler 300 (300C with 5-speed transmissions, 2005 to 2012).
    • Chrysler Crossfire, (from 2004 to 2007).
    • Jaguar XJ and XKR Supercharged, (from 1998 to 2003).
    • Mercedes C55 AMG, CLS55 AMG, E55 AMG, G55 AMG, ML430, S65 AMG and others.
    • Sprinter Vans, 2004 to 2012 (Dodge, Mercedes, Freightliner).


Features of the NAG1

The NAG1 transmission was built with an  electronically controlled 5-speed transmission system with a lock-up clutch in the torque converter. The electronic controls help the NAG1 gears to be activated hydraulically.

Moreover, it provides a precise adaptation of pressures to the respective operating conditions. In this case, the gears can be shifted by combining three multi-disc holding clutches, two freewheeling clutches, as well as three multi-disc driving clutches.

On the other hand, the fifth gear of this transmission is an overdrive with a high-speed ratio. Also, the ratios for the gear stages can be gotten by three planetary gear sets.


Benefits of NAG1 Transmissions

Some benefits offered by the NAG1 transmissions are:

    • Increased gas mileage.
    • Increased service life.
    • Increased shift control.
    • Reduced maintenance costs.
    • Enhances step-ups through the five gears.


NAG1 Transmission Problems

Despite the benefits of the NAG 1 transmissions, some problems were evident in them. For starters, Chrysler discontinued the use of this transmission in its products and the reason was attributed to the transmission’s use of electronic controls.

On the same note, earlier versions of this transmission were said to have a short lifespan. The latter was linked to the transmission’s sensitivity to fluid, slow shifting, and transmission filler tube o-ring leaking.

After upgrades, these problems were eliminated in the transmission. Other problems that may be noticeable on the W5A580/NA include the following:


1. Shudder

A shudder vibration or high-frequency buzzing may be experienced while using the NAG1 transmission. This problem may be evident when the acceleration is applied lightly and there is a partial application of the torque converter clutch in 3rd, 4th, or 5th gears.

The reason this occurs can be attributed to the passage of water past the transmission oil fill tube/dipstick seal. What’s more, contaminated transmission fluid can lead to sticking or slipping. Moreover, this transmission was extremely sensitive to the fluid quality.


2. Slipping, Erratic Shifting, or Reverse Gear Engagement

A notable problem with the W5A580 transmission is its ability to slip between gears. There could be a hard slam or erratic up or downshifts when the transmission engages its Drive or Reverse.


3. Overheating

Another cause of concern for the W5A580 transmission is overheating. If the ATF is unable to remove the heat that is created inside the transmission as its parts move and create friction, it could lead to overheating.


Operation of the NAG1 Transmission

The NAG1 transmission control was sectioned into electronic and hydraulic control functions. For starters, the electronic transmission control helps in gear selection and matching the pressures to the torque that is meant to be transmitted.

On the other hand, the hydraulic elements in the electro-hydraulic control module take care of the transmission’s power supply. Moreover, the oil supply to the hydraulic elements is transmitted through the connection of the oil pump with the torque converter.

There is also the Transmission Control Module (TCM) that helps in the precise adaptation of pressures to the matching operating conditions. It also helps in the engine output during the gearshift phase which could result in the improvement of shift quality.

Also, the engine speed limit can be attained in each of the gears at full throttle and kick-down. There’s also the potential for a change in the forward gears as the user drives, however, the TCM uses a downshift safeguard which helps to prevent over-revving the engine.

The benefit of this is that the system brings about the advantage of flexible adaptation to different engine and vehicle variants.


The Bottom Line

An overview of the NAG1 transmission shows that it was built to have high quality and stand the test of time. And most importantly, this transmission was used in a good number of cars which is evidence of its functionality.

Nonetheless, it is worth noting that it came with its own problems, and as such, it could be compared with other transmissions that had the same issues. Over and above that, the NAG1 transmission is worth the attention given the revamped specs it featured.


‘Tis the Season for Performance Transmission Upgrades

'Tis the Season for Performance Transmission Upgrades - Gearstar

It’s that time of the year when you get on the road with your friends and family. But don’t let a laggy ride drag you back, try some performance transmission upgrades that can turn your current car into your dream ride.

There is so much more a high-performance transmission coupled with a torque converter or drivetrain components can do for your vehicle, and for starters, it can improve its horsepower. All you need is DIU upgrades, and where you get stuck, you can employ the services of a professional to give your ride a boost even in the winter cold.

It’s the moment of celebration and as such, even the car you spend a few minutes in should bring you joy. If you agree, then these are the performance transmission upgrades you should try to enjoy the jingle bells season.


Why You Should Optimize Your Transmission for Increased Performance

Here are some reasons why your ride needs a performance transmission upgrade.


1. Engine Produces Torque that Can be Handled

Performance transmission upgrades are important for your car since it ensures that your engine does not produce more torque than what can be handled by the transmission. If that happens, a lot can go wrong which is usually evident in worn synchros, broken shafts, and bent forks.


2. More Power Can be Handled

It is also essential to upgrade your transmission so that it can handle more power, and the same applies to the transmission’s gear ratios to have increased performance. For instance, if you have a GM 4L60/E series transmission which was notably used in performance vehicles, it may not deliver to its best capability due to old-school mods.

Old-school mods are unable to improve the durability of your ride when it comes to extreme racing applications. Modern parts, on the other hand, are able to handle modern horsepower.


3. Improved Acceleration

A performance upgrade to the transmission can enable the engine to spend more time in the power band’s sweet spot. It is, however, worth noting that this might not impact the peak horsepower that is getting to the ground.

Nonetheless, the average horsepower that is put to the ground is increased thereby giving an improved acceleration that makes for a quicker 0-60, quarter mile or lap times.


Performance Transmission Upgrades

Your car’s power and ability to regulate heat all lie in its transmission and as such, this is such a powerful component. You would often need to do the following to get a good performance transmission upgrade:

  • Rebuild manual
  • Rebuild kit
  • Shift kit
  • Accumulator pistons
  • Separator plate
  • Torque converter


1. Rebuild

A great place to start is to replace or rebuild your transmission in a bid to improve its performance. It’ll be one that can handle payload more efficiently, and as such, what you’ll get is a faster and more powerful transmission. When it comes to rebuilding your transmission, you can rely on a car repair shop to do it for you.

In this case, your duty is to ensure that the shop uses the highest-quality OEM transmission parts and has skilled technicians to rebuild your current transmission. The result will be quite rewarding if either of these is in place since it’ll take a good technician to make the most of the quality parts you will be offered.

On the other hand, there are rebuild manuals for automatic transmissions, hence, if you want to do the upgrade yourself, you can be armed with one of these. A good resource manual centers on various aspects of how to work with the transmission in your car including the assembly, dis-assembly, diagnosis, troubleshooting, etc.


2. Rebuild Kits

There are also rebuild kits you can work with and if you choose to do it yourself, this type would prove useful. Let’s say you’re working with a 4L60E transmission, then you can settle for a standard better-than-stock kit with a molded piston kit or a high-performance rebuild kit.

Depending on which you settle for, it will determine the things you can do to your transmission and how well you can optimize your ride. The high-performance kit sometimes features the following: Raybestos Stage 1 clutches, a Kevlar band, a new filter, Kolene steel plates with 8 clutches 3-4 pack and a full bushing kit.


3. Shift Kits

Shift kits are also required in performance transmission upgrades. The 4L60E takes advantage of one of two kits most times, it is better to use one of two shift kits.

Some of these are the TRG-SK4L60E, and the TRG-4L60E-HD2. TRG-SK4L60E helps to prevent, correct, and reduce problems that may be associated with shift performance.

On the same note, it fixes harmonic bounce that may wear out the pump and valves and thereby, cause shuttle shifts.


4. Schedule a Transmission Upgrade

Now’s the time to take action, and schedule a transmission upgrade with a reliable company. In this case, you’ll be getting a high-performance transmission upgrade, and therefore good quality that can give a significant boost in your ride’s speed.

Moreover, such a company is one that has a high level of experience when it comes to high-performance transmission upgrades for vehicles. The same applies to whether it is an automatic or manual you are driving since the transmission in either of these can be upgraded.


5. Accumulator Pistons

There are also accumulator pistons that need to be replaced, and they are usually recommended in the case of a 4L60E rebuild. If they aren’t replaced, these may tend to ruin your transmission. In the 4L60E, a great place to start would be to replace the forward accumulator piston a well as the 1-2 accumulator piston.


The Bottom Line

Now it’s your turn to implement these performance upgrades on your car to improve its horsepower this season. The goal is to have a ride that can handle the impact of the winter given that this season is usually accompanied by snow and ice on roads.

And if you still want to transport easily, these tips can show you where to begin and the transmission in your car that is in dire need of upgrades. Therefore, don’t assume you’ve got the perfect ride, but go out there and do it.


Using This Vehicle Winter-Ready List, and Checking It Twice

Using This Vehicle Winter-Ready List, and Checking It Twice - Gearstar Performance

Winter’s here, and that means your ride needs to revamped to handle the ice, snow, and sleet on roads. A vehicle winter-ready list, for instance, will ensure that your car can withstand the harsh weather, thereby enabling you to drive smoothly and seamlessly as if it were summer.

Thus, winter won’t be something to detest since it does not mean you’ll be stuck indoors for hours unending without taking a therapeutic ride. So, how do you begin? Use the vehicle winter-ready and car maintenance checklist outlined below, and try these tips to ensure that your ride is ready for the weather.


Vehicle Winter-Ready and Car Maintenance Checklist

To protect your car, use this vehicle winter-ready list to help ensure a smooth along rough surfaces. Do the following below.


1. Check Your Windshield Wipers and Lights

The ability to see clearly as you drive through the snow is important, which is why you should check your windshield wipers if they are working properly. It’s even better if you replace the windshield wipers with winter blades that can help to wipe off the snow and ice that will be on the windshield.

Much more, a windshield washer tank with deicing fluid will remove the ice build-up and save you the extra time of waiting for it to defreeze. On the other hand, you also need to inspect your headlights and tail lights if they are working properly since it will provide good illumination when you’re out late.

You need to see the snow or ice clearly to maneuver through it, and if the lights are yellow or dim, clean the lenses or replace the bulbs entirely.


2. Protect Your Car’s Exterior

Did you know that you can winterize your vehicle’s exterior? It involves washing and waxing the car’s exterior to prepare it for winter. But here’s what it looks like:

It’s no surprise if you still have last season’s buildup on your car. That may be the case, but taking the step to scrub this build-up away can be useful.

Once that is in place, you can proceed to apply quality wax on the car to give it maximum protection against the impact of snow and road salt.


3. Maintain Your Car’s Battery

If you’re using the same battery from summer, the season’s heat could have affected the quality of the battery thereby causing it to be weak. This weakness is evident in the car’s inability to start on a very cold morning since the battery it totally drained.

On the other hand, you can ascertain the current state of your battery by performing a battery and charging system test. It will enable you to know if you need to purchase and replace the existing battery with a new one as a defense against the cold weather.

Nonetheless, a new battery may not guarantee that your car is safe proof for winter if you live in extremely cold areas. As such, the battery may have to be paired with a maintainer or trickle charger. Another thing you can try is to disconnect the battery from the car in a bid to prevent unnecessary power drainage.


4. Change Your Car’s Oil

Cars can either use synthetic or conventional oil, and synthetic oil has shown to offer several benefits over the latter especially in cold temperatures. For instance, synthetic oil warms up faster in comparison to conventional oil, and it also tends to flow freer at low temperatures.

As a result, the engine’s moving parts are protected immediately once the car is started. Cold weather starts are also easier when the car is running on synthetic oil.

That being the case, a winter vehicle maintenance you should also try is to change your car’s oil. In this case, use a full-synthetic oil that is appropriate for your car instead of relying on conventional oil it may currently have.


5. Examine Your Tires

A new set of snow tires for the winter is one more thing you should consider. But first, inspect your tires and if the treads don’t have enough depth, then you need a new pair.

The aim is to get as much traction as possible to enable the tires to handle the treacherous roadway conditions. Over and above that, it is expected that every 10-degree drop in air pressure could cause a decrease in tire pressure by one pound.

Hence, you also need to check the inflation of your tires, since an under-inflated tire can reduce handling and traction. It could also affect your vehicle’s fuel economy, asides from the obvious fact that the tires will tend to wear down faster.


6. Inspect Your Fuel Injectors

Clean fuel injectors can also make your ride powerful this winter. It all boils down to the fact that cold temperatures can cause performance issues to a vehicle’s fuel system. Some of these problems may be evident in hard starts and rough idling. The same can be said about the presence of water in the fuel system since it can spring up several issues.

This, therefore, brings about the need to maintain clean injectors, by employing a fuel injector cleaner. A cleaner of this nature will help with the restoration of lost power and prevent several performance issues from arising. All you have to do is add the fuel injector cleaner to the gas tank as you fill-up.


7. Check Your Antifreeze

An engine’s cooling system has a liquid that is made up of a blend of water and antifreeze. Antifreeze is an important winter chemical and it could contain ethylene glycol or propylene glycol. These chemical compounds in the antifreeze help to prevent freezing and expansion of water.

That being the case, you need to measure your car’s antifreeze strength using an antifreeze tester or let a mechanic do it on your behalf. The aim of the test is to determine the lowest ambient temperature of protection that is offered to the engine from freezing.


8. Inspect Your Car’s Thermostat and Radiator Cap

The thermostat and radiator cap are useful in the car’s heating and cooling system. The thermostat helps to provide the heat needed to the car, and if it fails, it can be attributed to the fact that the corrosion has occurred or the coolant has not been changed frequently.

On the other hand, the radiator helps to keep the antifreeze in your vehicle in place. It also ensures that the entire cooling system is pressurized, thereby increasing the boiling point of the coolant.

What’s more, it is important to check the radiator cap for any leakage signs or replace the cap with a new one if its been years already since you’ve used it. The reason is, a leaking radiator cap can lead to an overheating of the engine and leakage of antifreeze.


The Bottom Line

The vehicle winter-ready list is for car enthusiasts who want to maintain the full functionality of their ride and ensure that the cold does not impact on it. If that’s what you want, then employ these tips for a good winter-weather driving as if it were summer.

The requirements on this list are quite easy to implement, and you can also employ the services of a professional to ensure you get them all right. Now, you can drive seamlessly without the fear that your vehicle could potentially break down this winter.

Overview of the 2004R Transmission

verview of the 2004R Trasmission - Gearstar Performance

It is quite common to find 2004R transmissions in salvage yards and its replacement parts in several auto part stores. The popularity of this transmission has been evident despite it being the lesser-known of two GM overdrive transmissions from the 1980’s – it has also been almost over three decades since it was launched.

What’s more, if you were going to upgrade your classic muscle car’s Powerglide two-speed or TH-350 three-speed transmission, then the better option will be the 2004R since it is a perfect fit for the build. On the same note, the 2004R would be the ideal transmission to use if you were trying to upgrade to your old muscle car in a bid to get more punch and improved fuel economy.

Now, here’s an overview of the 2004R transmission that will give you more understanding of what this transmission offers.


2004R Transmission Spotlight

The 2004R is a four-speed automatic transmission that was launched by General Motors for the 1981 model year. This transmission can be used in several GM passenger cars since it was designed with a Chevrolet and a B-O-P bell housing bolt pattern. It was also produced with the Oldsmobile, Buick, and Pontiac patterns.

This transmission’s driveshaft, bell housing, and mechanical speedometer enabled it to be a perfect fit for vintage cars. What’s more, the 2004R’s sturdy build and torque capacity make it a better non-electronic overdrive transmission for GM classic cars.


History of the 2004R

The 2004R was designed to be a continuation of the Turbo Hydramatic line of GM transmissions. This automatic overdrive transmission could be found in high-power GM trucks and cars such as Pontiac Firebird Trans-Am and Buick Grand National.

On the other hand, the production of the 2004R  was discontinued in 1990, and the transmission was replaced with the 700R4, and iterations of the latter including the 4L60 and 4L60-E.


2004R Transmission Powered Vehicles

The 2004R was used in several GM B-body vehicles – it was also employed in C-body vehicles, G-body vehicles, and D-body cars. Nonetheless, the cars that came with a 2004R transmission include:

    • 1981-84 Buick Electra
    • 1981-90 Buick Estate Wagon
    • 1983-87 Buick Regal
    • 1981-89 Cadillac Fleetwood
    • 1981-89 Chevrolet Caprice
    • 1984-87 Chevrolet Malibu
    • 1984-88 Chevrolet Monte Carlo
    • 1985-87 GMC Caballero
    • 1982-83 Jaguar ZR W L6 220 3.6L S S
    • 1986-90 Oldsmobile Custom Cruiser
    • 1983-89 Pontiac Parisienne

    • Computer Controlled: No. Instead, it is controlled by TV Cable and a lock-up torque converter


2004R Identification

It’s quite easy to differentiate the 2004R transmission from the 700R4, TH350, and other transmissions that were made by General Motors. For starters, the transmission identification can be located on the plate on the right side of the case that is towards the tail shaft.

The plate has a two- or three-letter transmission code which is written in large letters. Another way you can go about it is to count the number of pan bolts of the transmission, and if it is 16, then it’s either the 2004R or 700R4.

But fret not, since there’s no confusion! The 2004R has pan bolts whose size tends to be smaller towards the end. In contrast, the 700R4 maintains almost a perfect square.

On the other hand, the 2004R may easily be confused with the TH350 since they feature the same dimension. Nonetheless, the TH350 has 13 bolts on its square transmission pan, which is considerably lower than the 16 bolts on the 2004R.


2004R vs. 700R4 vs. TH350

The 2004R transmission can be compared side by side with other two overdrive transmissions which were also made in the 1980’s – and these are the 700R4 and TH350. For starters, it is similar to the 700R4 even though it is the weaker variant of the 2004R/700R4 duo.

Needless to say, a 2004R transmission that was made towards the end of the production year is still better than an early 700R4. It is also worth pointing out that the 2004R was not necessarily meant to compliment the 700R4 since they achieved the same functionality.

This transmission was, however, fits into the engine bays of existing models where the 700R4 could not. On the other hand, the 700R4 has the same dimension and bell housing bolt pattern as the TH350, which made it interchangeable in vehicles that were designed for the TH350.

What this means is that classic cars that were originally built to use the TH350 three-speed transmission can easily swap to the 2004R without any major modifications being made. For instance, there’s no need to shorten the original driveshaft.


2004R Transmission Problems

One of the 2004R transmission problems is the transmission not going into gear. Here, the 2004R transmission may fail to go into gear even after the linkage has been hooked up properly.

It may not respond when you also try a test of shifting it through all the gears (R/D/3/2/1). Nonetheless, you can proceed to check the fluid level using the dipstick to ensure that there is enough fluid in the torque converter.

You also need to ensure that the shifter mechanism is working properly and the pump is moving fluid. Slipping could also occur when using the 2004R transmission and it could be a signal that your ride needs maintenance.

Slipping is usually evident in slow or delayed acceleration, hard shifting, or strange smells. Nonetheless, you need to check that the fluid level is not low and that the valve moves and returns freely.


The Bottom Line

An overview of the 2004R transmission shows that this transmission may have been replaced with newer transmissions, but it was still useful when installation space was a factor. It was a perfect fit in cars that used the TH350 transmission, and there was no need to carry out major modifications.

Also, several cars ranging from Buick, Cadillac, and Chevrolet used this transmission. What’s even more remarkable is the sturdy build of this transmission that makes it a good choice if you want to upgrade your old muscle car.


How High-Performance Transmissions Went From Zero to Hero

As technology advances, most products we are using on a regular basis are becoming more efficient. This enables them to offer us a higher level of performance. Transmissions are no exception to the rule. It is beneficial to understand what transmissions are, what their history is, and what you need to know when purchasing one of your own.


Transmission Talk

“Transmission” is a term that is used to describe the mechanism that channels all of the horsepower that is generated inside of your motor vehicle.

Imagine the way in which the power from your engine gets to your wheels. The motor is capable of making that power, but without the transmission, it would be useless. Add a transmission into the equation and then there is a fully-functional motor vehicle.

Your transmission can also enable you to quickly adjust gears via the clutch. The clutch plays a really important role because it is responsible for separating the engine from the transmission and then re-connecting them both when it is necessary. This is what allows the transmission to change gear ratios so that you do not have to shift gears manually.


A Brief History of Transmissions

You can trace the origins of what we would consider to be modern transmissions all the way back to the year 1904, when the Sturtevant brothers developed what was known as the ‘horseless carriage’ gearbox in Boston, Massachusetts. The unit that they created featured two forward speeds that could be changed by flyweights that were driven by the engine.

Naturally, a higher speed would make the high gear engage, while a lower speed would do the opposite. Unfortunately, the metallurgy in the early 1900s was not as good as it is today. This led to a number of these gearboxes failing without warning. Luckily, improvements have come a long way.

The early part of the 20th century would lead to a number of important developments in the field of mechanics. In 1906, Henry Ford would release a special two speed plus reverse transmission that could be manually controlled using pedals.


The Turning Point

But, it was not until 1932 that we would see the first transmissions using hydraulic fluid.  The inventors of the first transmission using hydraulic fluid is by two engineers, Araripe and Lemos, who then sold their creation to General Motors. However, in the Wall Street Journal, an article appeared crediting ZF Friedrichshafen for the invention.

By the 1960s, three-speed units that featured torque converters had become incredibly popular. At this point, whale oil is being taken out of transmission fluid, something that shows real ingenuity. Fast forward to the 1980s and the three-speed units were already evolving to overdrive-equipped transmissions. These new developments involved four or more different transmission speeds and a lock-up torque converter that would improve fuel economy.

As amazing as all of these improvements and inventions might sound, the really interesting things have occurred over the course of the past two decades. We have seen everything from the first six-speed transmission to the first nine-speed automatic transmission in this small window of time. We can only imagine that things will keep improving as more time passes.


What Should You Look for When Purchasing a Transmission?

Consider what you want before you begin considering purchasing a new transmission. You can put as much money as you want into your motor vehicle, but all of that money won’t mean a thing if your transmission decides that it is going to fail.

Because mainstream transmissions are so standard, majority of car garages will have them in stock. But, there is an alternative solution.

Question whether or not to invest in custom high-performance transmissions. High-performance transmissions are both designed and built to meet the exact specifications of your own car, ensuring that everything fits together and works in perfect harmony.


Are Transmissions Really THAT Important?

Without a transmission, you would not have the power that the engine generates from your car to the wheels. It would be impossible. Replacing a transmission can cost a lot of money. Because it’s costly to replace a transmission, it’s a good idea to provide it with regular maintenance.

If you want to customize your ride, consider looking into high-performance transmissions. Remember that the quality of transmissions is always improving. With these improvements, it is worth considering whether or not an upgrade would be worthwhile.
