hi im new too forums and looking for help

[circa09]

I currently drive a 2000 gp gt coupe. My transmission shifts perfectly until my trans warms up. Any ideas on problem?

How does it shift after it warms up?

[circa09]

Every gear hard shift and if I give it gas it will shake entire car before it shifts.(shakes only at higher rpm) I checked my trans fluid color its good. Does not smell burnt. And the level is perfect

Soungs like the problem my last GP had. Turned out to be a solenoid in the transmission. When the trans takes longer to shift than it expects it will shift at max pressure until the car is shut off. Next time you start it, you will get normal shifts until a long shift is detected and then the problem is back. If I remember right, the code was P1811.

This will help you:

Harsh Shift, P1811

Okay awesome. If that is the case.. how much does it cost or how hard is it too replace the solenoid?

[Silver GTP]

I had a trans shop do it and had it rebuilt. I was planning on keeping that car for a while, but got rear ended and totalled it. The solenoid isn't that expensive, but they said you had to pull the trans to replace it so the labor was high. I think I've seen people on here say it can be done in the car if you know what you're doing.
