Automatic Transmission problems of the 2001 Saturn SL2

2001 Saturn Sl2 transmission will slam when placed in reverse replaced fluids and let run in reverse position with emergency brake set and backed up against a tree to try and clean valve body - no success.

My 2001 Saturn Sl2 recently developed a sever 'buck' in the automatic transmission when it shifts. That is, when it changes gears it either slams into the next or hesitates then slams. Reverse is the most severe as it slammed so hard that it broke the muffler from its mount at the very rear of the vehicle. The fluid has been changed ahead of schedule on the transmission, and the oils changes have also been timely. I've read on several forums that this is not only symptomatic of the make and model of my car, but predominate in quite a few of the models in the Saturn family. I've since had the fluid changed to no avail of correcting the problem. . Read more...

Dealer has not been notified as of yet. When transmission is switched to reverse, the vehicle gives a very strong jolt backwards, like a hard-knock engaging of the gears, so strong I am afraid it could cause a whip-lash someday.

The contact owns a 2001 Saturn Sl2. While driving 30 mph, the vehicle jerked and slammed into gear. The dealer stated that the motor mount failed and they changed the transmission fluid. Approximately ten days later, the failure recurred. The contact took the vehicle to a mechanic and he stated that the lining inside the transmission separated, which allowed debris to enter the gears and valves. As of November 27, 2007, the mechanic had not repaired the vehicle. The failure mileage was 50,000 and current mileage was 74,000.

After turning the vehicle on and when placing the gear in park or neutral vehicle jumped forward. Dealer examined the vehicle, and found that that valve body assembly had been replaced.
