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.

I have a 1999 Oldsmobile Bravada of which I have just found out there is a tsb on its transmission stuck in 3rd gear/reverse reaction shell brakage. I have inquired with GMC and a local dealership and neither told me of this. My vehicle only has 40,000 miles on it and according to the tsb, Oldsmobile service personnel is required to repair it free of charge but they have offered me a 50/50 split. I feel this is unacceptable. My car is still considered brand new even though my 36,000/3yr warranty is up and with the amount of miles it has on it, it should not be having a transmission problem. I did not read about a warranty clause related to the tsb and feel oldsmoble is not honoring the tsb as it is stated. I have been told by both Oldsmobile and the dealership repair to my vehicle is imperative.
