3 Common 4L60e Transmission Issues

The 4L60E transmission is the most commonly utilized automatic transmission in American vehicles today. There are millions of these transmissions currently in use and as a result of their widespread omnipresence, a number of problems tend to take place on a fairly regular basis.

If you learn about the common issues, it is easier to find a shop that can fix the problems once they start to take place. Let's take a closer look at these concerns and the best ways to address them, so that your 4L60E transmission is always running at peak capacity.

1. No Reverse

Those who already own a 4L60E transmission are probably well aware of the fact that there is no reverse to be found and while this is a fact that doesn't seem to bother most people, it can lead to certain issues over the life span of the transmission. The clutch disks will often wear out faster as a result and the best way to find out if this is taking place is to check your transmission pan for debris.

There are other signs of wear and tear that need to be monitored in order for you to receive the best possible transmission performance. The reverse circuit and the booster value may also experience unwanted wear and tear, so be sure to check for signs of strain on a regular basis. If you cannot handle these tasks on your own, enlist a professional.

2. Harsh Gear Shifting

If you are someone who regularly shifts from first gear into second, you will notice that these transmissions experience wear and tear due to the harsh nature of these shifts. That's why you need to monitor the long term health of the transmission to experience a lessened amount of strain. Your throttle position sensor may also be defective.

In order to check your throttle position sensor, you'll have to take a closer look at the voltage. If the voltage does not decrease or increase in a manner that is linear and smooth? This is a sign that you need to take a closer look at the overall health of the transmission. Those who have confusion are welcome to check their shop manual for more information.

3. Shuddering

In addition to the problems associated with harsh gear shifting, there are also shuddering issues that take place when the driver is attempting to shift while they are in full throttle. The 1-2 accumulator may to be blame for the problems experienced by the driver and it is important to check on the inside to make sure that no springs are broken.

The piston inside of the accumulator could have developed cracks and these cracks are also responsible for any potential shuddering that is taking place. The walls of the piston bore will also have to be inspected on a regular basis. Think of the vehicle's transmission as a new pair of shoes. While a scuff or two isn't the end of the world, it does signify that certain wear and tear has started to take place.
