Pontiac Grand Prix GTP Problems

Noise from front section of supercharger
The supercharger may develop a noise in the front section of the supercharger assembly. The is due to a worn coupler. Our technicians tell us that a remanufactured coupler section is available from aftermarket suppliers.
Rubber Transmission Cooler Lines Can Leak Fluid

An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.

Inspect transmission/fluid every 30,000 miles

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed.

Bought this car with 22,000 miles in 2004. I love my car, would never trade it in, unless I could get another one!! Starting to need some repairs (150,000) but nothing out of the ordinary. I hope this one runs forever!!! My sons are constantly arguing who will get the car when I can no longer drive, LOL!
