4L60E

4L60E refers to a series of automatic transmissions from GM (also known as 4l60 e). The 4L60E was developed by GM for performance and durability, making it a popular choice for a wide range of vehicles. They are designed for longitudinal engine configurations and include 4 forward gears and 1 reverse gear.

At Gearstar, we’re known for using upgraded or remanufactured components. We take great pride in our superior parts, attention to detail, and seasoned technicians. Only one person will build your 4L60E transmission -  this is how perfection is achieved.

Basics About The 4L60E Transmission

The 4L60E is an automatic shift, four-speed overdrive transmission that has the reputation of being one of the best automatic transmissions ever made. Before the 4L60E was produced, there was another trans called the Turbo 700R4. 

The 4L60E was first introduced in 1982, with the “E” standing for “electronically shift-controlled". GM 4L60E transmissions are rated up to 450 horsepower and 425 ft/lb torque, and can be custom-built by the team here at Gearstar. 

The 4L60E is very impressive and can be used in both trucks and cars. Its robust design allows it to handle high torque loads and withstand demanding driving conditions, making it suitable for heavy-duty applications and long-term reliability.
 

Key Features of The GM 4L60-E

Two Distinct Versions - When talking about GM 4L60E transmissions, there is the “early” version and the “late” version. The early version is from 1982-1989, while the late model is from 1996-2010. The 4L60E itself was produced and used in a wide range of GM vehicles from 1993 to 2021, covering many years of production. You can easily identify the later version of the 4L60-E based on its removable bellhousing. Another determining factor is the six-bolt hex rear output.

Versatile Applications - The 4L60-E is known for its broad applications across various models, including trucks, performance cars, and SUVs such as the Chevrolet Suburban and GMC Yukon, making it a versatile choice for many different driving needs.

Impressive Shifting Patterns and Performance - The 4L60E transmission delivers smooth, precise shifting patterns that enhance both everyday drivability and high-performance applications. It features carefully calibrated gear ratios—2.45:1 in first gear, 1.45:1 in second, 1.00:1 in third, and 0.69:1 in fourth—that provide a balanced mix of acceleration and efficiency. Its advanced valve body and TCC (torque converter clutch) regulator valve work together to control the lock-up torque converter, reducing engine RPM at cruising speeds and improving overall fuel economy.
 

Advantages of the 4L60E Transmission

If you are considering the 4L60E, there are many benefits to think about, including (but not limited to):

Strength - The 4L60E is well-regarded for its strength, especially when properly built or upgraded for high-performance applications. Its robust internal components, including a strong planetary gearset and reinforced cases, allow it to handle moderate to high horsepower levels, making it a popular choice among street and strip enthusiasts alike.

Durability - Known for its long service life when maintained correctly, the 4L60E stands out for its durability. With proper fluid changes, cooling, and tuning, this transmission can deliver years of reliable performance. Many custom builders also offer upgraded parts that eliminate known weak points, further extending their lifespan under demanding conditions.

Broad Usability - One of the biggest advantages of the 4L60E is its wide range of compatibility across General Motors' vehicles, including trucks, SUVs, and performance cars from the 1990s through the mid-2000s. Its electronic control makes it easily adaptable to both factory and aftermarket engine management systems, offering tuners and builders a high degree of flexibility.

Great for Jeeps - Thanks to its compact size, strength, and availability of aftermarket adapters, the 4L60E has become a favorite swap option for Jeep owners. Whether you're building a rock crawler or an all-terrain overlander, the 4L60E provides the gearing and torque handling needed for off-road performance.

Modular Design - The modular nature of the 4L60E makes it easy to customize and upgrade. From torque converters to valve bodies and input shafts, nearly every component can be tailored to meet specific performance goals. This design also simplifies repairs and replacements, reducing downtime and overall cost for enthusiasts and shops alike.

New Versions Coming Out - Aftermarket manufacturers, like us here at Gearstar, continue to push the limits of what the 4L60E can do by releasing new and improved versions. Whether it's upgraded internals, enhanced tuning options, or bolt-in performance kits, the platform continues to evolve, making it a smart choice for future-proofing your build.

Impressive Power - While stock versions of the 4L60E are designed to handle modest power levels, custom builds can support over 500 horsepower and beyond. With the right upgrades, this transmission can manage impressive torque figures without sacrificing reliability, making it a powerhouse option for performance applications.

Frequently Asked Questions About The GM 4L60E Transmission

What year did GM stop using the 4L60E?

GM began phasing out the 4L60E around 2013, transitioning many of its vehicles to newer 6-speed options like the 6L80E. While some platforms used it slightly longer, most GM vehicles stopped using the 4L60E by the early 2010s. However, it remains a popular choice for swaps, rebuilds, and performance applications.

What GM vehicles have the 4L60E transmission?

The GM 4L60-E can be found in just about every GM rear-wheel drive such as the Sonoma, Chevrolet Tahoe, Safari, Astro, Yukon, Firebird, Camaro, and Corvette

What are common problems with 4L60E transmissions?

Some of the most well-known issues with the 4L60E include slipping or delayed gear engagement, 3-4 clutch pack failure, torque converter clutch wear, worn valve bodies, and harsh or inconsistent shifting

Our custom-built 4L60 E transmissions are upgraded to eliminate these weaknesses, using high-quality components and precision tuning.

What kills 4L60E transmissions?

Several factors can lead to premature failure, including overheating due to poor cooling, towing heavy loads without the proper upgrades, lack of maintenance, including not changing the transmission fluid frequently enough, and factory design flaws in clutches and valve bodies.

To prevent these issues, our rebuilds include heavy-duty clutches, improved servos, better cooling, and dyno testing for reliability and longevity.
