Two problems related to automatic transmission have been reported for the 1999 Oldsmobile Bravada. The most recently reported issues are listed below.
Transmission reaction sun shell failure occurred when entering highway at legal speed. Avoided accident, but condition is extremely dangerous and somewhat common to all gm 4l60e transmissions. Dealer diagnosed failure and stated that this was a common failure in this transmission due to a defective design of the reaction sun shell. Part is improperly welded/heat-treated. Gm has redesigned the part and offers goodwill repairs at their discretion. Gm decided that my dealer-maintained vehicle was not worthy of a goodwill repair?, although the service manager recommended transmission replacement due to the pristine condition of my vehicle. Cost $2152 to repair, but how many accidents or deaths has this event caused over the last ten years? I would believe at least one and gm has escaped the recall this part failure deserves. Car has been maintained by dealer in accordance with required intervals. Transmission flush is not recommended until 100,000 miles, but this vehicle has had fluid flushes; by the dealer, @ 35k and 78k. Failure occurred 4 months after service @ 82k.
While driving at 55mph, rear wheels felt as if they locked, vehicle began to fishtail or swerve in rear end. The vehicle accelerated over the median and hit an oncoming vehicle. Neither drivers side nor passengers side airbags deployed. Consumer states that the roads were wet and it felt as though the rear tire hit a water pocket, consumer states that vehicles brake or awd system failed also due to the skid marks, there were four injuries in the accident.
