Vehicles with a 6speed automatic transmission may develop one or more of the following faults related to a broken 35R clutch wave plate inside the transmission: Illumination of the Check Engine Light with code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723, loss of reverse gear, slipping or harsh 3rd or 5th gear shift. Removal and dis-assembly of the transmission will be required to replace the broken 35R wave plate. It is also extremely important that all debris from the failed part be cleaned from the transmission while it is disassembled in order to try and prevent future problems.

Have an 2008 Enclave at 45,700 miles and suddenly it feels like the transmission is stalling or sticking. Won't reverse and the the Transmission Hot Engine Light is on. Can smell the transmission fluid and can't go past 40 without loud engine noise. Is there something going on with the transmissions as a whole? any recalls for transmission problems?
Transmission would not shift. Car running. Dealer recommended replacement of transmission at a cost of

Transmission slipped once and engine light came on. Car would not exceed 40 MPH.

At first the vehicle would shake and stutter while in reverse. Afterwards, the vehicle would have hardshifting and wouldn't engage while in drive...just accelerate! Vehicle stalled out and was towed to the dealership. They did a complete "teardown" of both the tranny and engine. The diagnosis is an internal damage to the transmission (wave plate), and a bearing in the engine came loose. I've researched this issue and am shocked that there has been no TSB or recall!! If this is an on-going problem, why hasn't GM issued a courtesy recall?

Car would not accelerate and would not go into reverse. The dealership had it for 7 weeks and finally put a new transmission in it. It runs now but not the same.

P0776 No Reverse. Says its a selenoid, but I'm betting on the wave plate.

Vehicle would not shift into reverse or past the low gear. Wave Plate issue expected. Vehicle not under any warranty and no recalls identified. Looks like I am out a few dollars (may need to refinance my house for this one) Thanks GM.
