I just recently bought a 2001 Trans-Am with the automatic new here but im guessing its the 4l60e trans.. Anyways i just took it for its first real test run and i was cruising at 50-60mph and it never downshifted the tach stayed around 3000rpm and it only dropped down when i let off the gas..

All help is welcome like i said im new to these but i gotta fix this its gunna eat gas bad this way.. all i can figure is maybe something in the programming?

sounds like you are in 3rd not OD, from a stop count how many times it shifts

Torquewrench87

Ok but what would make it not go into overdrive?

maybe it has 4.10s or something?, how does pull from a stop

Torquewrench87

Oh it pulls hard from a stop breaks traction with the traction control on real easy and like i said i have no idea what is and isn't modified as i just bought the car but under the hood looks very stock has the original air box only thing i know is that it might have a flowmaster on it or some other performance muffler, it even still has the stock rectangle exhaust tips on it stock exhaust manifolds... when i was driving it at 55mph and it was at 3k+/- rpm i put it from OD into 3rd and it seemed to rev higher.... and lastly the only stupid question is the question left unasked... come on im used to carbs and TH350's all this computer stuff is new to me seems like it controls everything!

Im almost 100% sure its the stock trans that came in the car, how can i confirm this?

Torquewrench87

According to those pictures its stock i guess its just not making it out of 3rd? im at work right now, im gunna pick up the pace on the ride home see if i can make it get into OD.. keep em coming guys


Thanks.

lockup module? That's my guess.

Torquewrench87

No check engine light on. no idea about the lock-up module and it has 174k miles on it not sure if its the original engine/trans.

I'm having the same problem. My builder told me it has to do with the 3-4 servo not engaging into 4th. It's getting stuck in third. They sent me a new washer to replace the one getting stuck in the servo. I'm gonna put it the new washer tomorrow and let you know if that worked. I'm still learning the in's and out's about these transmisions as well.

Well yesterday coming out of the parking lot where i work at i decided to have some fun turned the TC off and gave it hell (that was fun!) lol well when i got out of town and onto the highway cruising at 60mph it was just around 1500rpm so i guess it just needed some tuff love lol all seems to be working as it should now.. this car must have sat for abit before i got her.


Thank yall for all the help, hope you get yours fixed also spyterus.

Well I did get it fixed! Glad to hear yours is good now. I've been troubleshooting mine for a couple of months now. These cars need constant TLC but they're bad *** when running good.
