    Ok everyone! I need some help! I have a 2000 Grand Prix GT 3.8L V6. I am having the transmission issues that plauge every Grand Prix of this year. It is shifting (almost like bucking) when it shifts. I have researched it a little and I've heard its the torque Converter Clutch or Pressure Control Solenoid. I don't know which it would be or if I have to rebuild or replace the tranny?? Does anyone know or have any suggestions on what it is or what price it would be?????

    I know this is an old post but it may help others with this problem.

    It's most likely a shutter in the torque converter. we added something from Oreilly auto parts made specific for this problem. It was a lube of some sort added to the tranmission fluid. So far it has cured it. Might try it. Otherwise, we were told the converter will need to be replaced if it gets worse.

    It may also have been the catalytic converter. had a similar problem with my 2002 and it just need a new one. some cars may still be covered by a warranty on the catalytic.
