I have a 2005 bonneville gxp pontiac with 68,000mi. with a northstar v8. It would shift hard after 20mi. I took it to dealer shop on april 17-21,23, 24,28,29 They have replaced powertrain celluar,stiil shift hard,then they replaced TCC solenoid,and during thier test drive they said gears fail out, just lost presure. Now they say its the pump shaftand/or transmission pump,I will have to pay parts and labor, they did'nt touch that piece of the transmission, I still do not have my car!! 5/10/09 please help with infromation.

Is this to suggest that it's fine for the first 20 miles? The fluid is naturally cooler then which is a clue that this may not be anything more than a trans fluid change to approved synthetic and bet it clears up! How often to you change the trans fluid? It loses it's original properties with heat and the bare bones mechanics of it are impacted. IMO synthetics tolerate heat better and if needed add a trans oil cooler,
