2001 Pontiac Montana transmission complaints
Page 2 of 2: complaints 11 to 20 of 20, newest first, as owners wrote them.
When the vehicle is placed in gear there is a scraping noise. This noise was first noticeable in reverse only. However it started happening in drive as well. Also when braking at intersections the engine completely disengages and free wheels. Then when accelerating again it takes a second or two for the transmission to re-engage. The dealership heard the noise and experienced the problem. Then the transmission completely broke on their drive during this problem's evaluation. The transmission had to be replaced after only 41,500 miles. There was internal metal debris throughout as well as lots of gear damage.
While driving, the front end of the vehicle vibrated. *jb the vehicle would hesitated when accelerated after a complete stop or when slowing. The dealer was unable to remedy the problem. The consumer requested a refund for the vehicle. Other problems are as followed: the vehicle felt as if it was going to stall when idled due to dirty injector(s), there was noise on driver side of the engine, the horn would go off by itself/dealer unable to duplicate, the cover in the rear hatch on the left side did not stay in place and reinstalled the panel door, the transmission had no reverse and grinds when placed in forward gears/removed transmission assembly and disassembled, there was clunking when in gear, the planetary gears were rounded, the transmission acted as if it wanted to take off, found a loose motor mount on the driver side and was tightened, the steering was stiff, and was noisy when turning right.

Van slides backwards while stopped on an incline if the foot is off the brake. This happens while driving and the transmission is in drive,if I stop on an incline and then release the foot brake to resume driving , the van rolls backwards. We spoke with the service department at the koons of manassas. We were told that this is a normal feature for this type of engine and nothing can be done about this. We request.you to look into this problem, thank you
Consumer states while stopped at an incline and foot off the brake, vehicle will begin to move backward, consumer feels this should not happen with a vehicle that is equipped with an automatic transmission.
