2001 Tranny problem

Postby Bunja23 [OP] » Aug 01 2012, 1:49pm

I'm new to this but I thought I would try. I have a 2001 silverado 1500. I was getting coolant in the transmission, but I got that taken care of. But ever since that the transmission is not running rite. Its a 4speed auto. If I would run it in 3rd it would run fine, when I shifts into drive and drops down to around 1500rpm it starts to buck and jerk. Now its starting to do it in 3rd. Any idea what it would be? I did change the filter and fluid. Truck has 159k on it. Thanks

Did you flush all the fliuid out? Coolant (and water) is the second worst enemy of the transmission (the first is heat). I'd bet if the coolant was in the transmission long it will have to be rebuilt. The coolant will destroy the clutch material. You will need a new converter as well because I'm sure the lock up clutch is ruined in it as well.

Thanks, As soon as the transmission started to slip I changed it 2 days later then it still did it, thats when I found out what the problem was then I changed it the next day again. A buddy of mine said something about a TCI module in the tranny needing replaced but I can't find what that is.

If water/coolant was in the transmission that long I'd say it's toast and needs overhauled.
