1999 Pontiac Grand Am SE 6Cyl3.4L - Transmissions & Drivetrains
Why does the car jerk really hard when shifting the car from park to reverse and/or drive?
The car also jerks/shifts really hard as you begin to accelerate. It seems as though it is having a really hard time shifting from 1st to 2nd gear. It also seems like it does a less severe jerk in the next shift. Additionally, it has started idling funny. The car will start normally and then begin to rev slightly on its own. The revving never exceeds 1k rpm. Any ideas?
