Reply, I purchased a gm 4L60E trans for my hot rod, was told it had 20k on it and it looks like it. If you find a lot of problems when you are shifting from 3rd to 4th, this could be the issue. There are situations in which the broken solenoid means the car will not move from neutral making the car is undrivable. This is due to the fact that the transmission fluid cannot be rerouted to the part of the transmission that would be making the next move. If this light is on, there may be a stored trouble code related to a bad shift solenoid. Otherwise, its also possible that the shift solenoid has been stuck open during the operation, or that the speed sensor has gone bad. This all happens when the transmission changes gears and you continue down the road. A loss of all gears can occur due to a total loss of fluid or pump failure. 3rd gear, on the other hand, has a ratio of 1:1, while 4th gear is meant to be used as overdrive. This is a quick look at the signs that can appear when you have problems with a faulty shift solenoid. Are you sure its stuck in first gear, Its probably in second.. The E part of 4L60E means electronic; this transmission has electronic control.

Magnus is the owner and main author of Mechanicbase. It replaced the 4L60. The 4L60E is made unique by being one of the first transmissions to use electronic shift control. Its 1st gear is set at a ratio of 3.06, while the 2nd gear drops to 1.62. In order to fiddle with, repair, or replace the VSS, the transmission will need to be completely removed. Although, tuning it down to a 1st gear ratio of 2.84 and a 2nd gear ratio of 1.55 is a good balance, especially for high horsepower applications. Reply, Same issue when replaced my transmission in my Chevy trailblazer. You may also notice that your car has a problem engaging some gears, and therefore it will skip to the next gear. Hopefully, diagnostics can work the problem out for you. There is a small allen screw on the back of the solenoid that sets the overall pressure range for the solenoid.
