I wonder all you GXP guys that had the tranny go, do you use the tap shift a lot?

A lot meaning more than 2-3 days a week.

Bryan, you might be on to something. On another note if the SS had tap shift, I'd use it everyday.

i never use tap shift, the bottom line is this crappy parts inside a tranny thats not made to handle all this power and torque, plus there is a service bulletin for the 05 for tcc, and to replace the tranny

iam with texasgxp i want to love my car but more problems then problems, here is another one this thursday i went to my car to get my smokes i look on my seat its wet look up and my headliner is completely soaked!!!

again had to fix the onstar antenna, and the problem was clogged drain tubes for the moonroof, unreal!!! iam sorry but i cant have this many problems with this car anymore, iam looking at either dodge srt-8, or an import, the quality from an import and the longevity is second to none

bye-bye gm
