The 10 Most Common Problems With the 4L60E Transmission

While the 4L60E transmission is considered one of the best by GM, it is not without its flaws. Unfortunately, transmission issues have been said to occur even with the best care and maintenance. 

Below are a few of the most common problems that are known to plague the 4L60E transmission, including why your vehicle cannot shift gears and how to know if your pump is bad.  

We also offer possible causes, fixes, and costs for your convenience. Please keep in mind that these aren’t definitive solutions for every case.

1. 4L60E Transmission Third Gear Problem

The most common gear issue for a 4L60E transmission is a loss of third gear. This problem typically occurs out of the blue. You can put the vehicle into drive and shift it into second gear without issue, and just as you try to go into third, nothing happens. It’s as if your vehicle is stuck in neutral and can’t proceed. This problem happens because the piston rubber seals have shrunk from age and heat.

The Fix

To fix this issue, usually, you’ll need a new piston and clutch. A new piston’s average cost is between $1,000 to $5,000, and the average price of a new clutch can cost between $900 to $1,800. Although, pricing will depend upon your vehicle and the shop you use.
