Thread: Does anyone else have this issue after getting a reprogrammed pcm?

I've noticed that after i installed my reprogrammed pcm, my gp will roll backwards on a decent sloped hill while it's in gear. Perhaps its pcm related and my tranny just decided to start having issues? I'm just curious if any of you guys have ran into this problem? I have a 97 gt coupe. thanks

torque converter...??? or Line pressure issue...

Mine will do that if steep enough, my carsis 200% stock, no major problems.

That's normal. Weight of the car overcomes the force applied in the torque converter by the engine idling.

As long as its not a sign of things to come, i'm okay with it. I just thought it seemed a little odd.
