This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.

Vehicle is experiencing a loud cluncking noise when turning a corner and accelerating at the same time. Also, vehicle is not downshifting to proper gear, causing a vibration throughout vehicle when driving at speeds between 35-45 mph. When changing to any gear from park position, vehicle will jerk. Manufacturer has acknowledged defect, but cannot fix it. Cause is unknown.
Vehilce experienced a grinding sound, whenever engaged on four high while making a tur.; also, appeared to disengage and reengage by itself. In regular drive, it intermittently jumped into gear from a stop position when accelerator pedal applied. Dealer notified.
The automatic transmission intermittently fails to engage on launch. There is a delay of 1 to 2 seconds before the transmission engages and the vehicle moves. The failed condition appears as if the vehicle is in nuetral and then slams into gear. The failed condition may be that the vehicle is actually trying to launch in 3rd and then down shifts after a delay. This is a potentialy dangerous condition that could result in an accident while crossing traffic or entering traffic. I have found via the internet that many owners of this vehicle are having this problem with both 1999 and 2000 models. This problem is very intermittent and can not be reproduced with regularity. Because the problem can not be reproduced I have not taken the vehicle to the dealer, it would be a waste of time at this point. The dealer will not be able to reproduce the failure. I have experienced the problem 3 times in 3 months and 3000 miles. It is impossible for vehicle owners to get GM to do anything because the problem is so intermittent. GM has to be aware of the problem from what I have seen on the internet. Please let me know if I can help in any way with your investigation. Thank you in advance for your help.
Accelerator would surge while in gear. Would shift from overdrive to low gear on its own. This happens when doing highway driving. The manufacturer has been contacted & knows of problem. Vehicle been in shop for over a month. There is no corrective solution to problem of surging & gear shifting.
Transmission shudder, forward or reverse, immediately after releasing foot brake to begin acceleration. Then between 18 and 25mph there is a vacuum leaking sound - whistle.
