2001 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl 4A)
This car was great for the first 50K miles then things started to fall apart. The catalytic converter went out at about 55K, and the transmission started operating real sloppy. From there the transmission went downhill. The transmission had a certain lag when you needed to accelerate and it started making funny noises. At 85K the transmission started dropping into gears and continued to sound worse. I just got rid of it before things got worse.
Stylish exterior design and decent engine power. Also, good sound system.
Terrible transmission!! It definitely needs to be redesign.
