Buick Enclave Problem
Average Mileage: 68,989 mi (4,775 mi - 126,000 mi)
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.

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.

Same problem, dealer said I was out of warranty on time but less than the warranty's mileage limit so GM is going to cover 1/2 of the cost of the repair. They quoted $1425 so my cost will be $712. Honestly I don't know if the $1425 is a fair price or not. My only recent transmission experience was having the bearings replaced in a '85 Jeep CJ7 transmission that I brought to the shop. That was $500 but I know there is more to this 6 speed tranny than my old 4 speed manual.
Transmission would not shift. Car running. Dealer recommended replacement of transmission at a cost of

Drove to post office, Enclave would not move in reverse. Called dealer to come tow. Don't have results yet.

Have had complete electrical system wiring (front to back) replaced within the first 20,000 miles. DVD/camera screen still goes black, occasionally. Have to pull over, turn car off, open and shut driver door, and re-crank to reset electrical. Had rear hatch motor replaced due to slamming shut on us with no warning. Right running light will not stay lit. DVD/radio screen will sometimes not power down after exiting vehicle. Have found dead battery three times, now carry portable battery charger pack in vehicle at all times. Now, at 67000 miles, transmission needs to be rebuilt. Revving engine, could not settle on a gear. Very rough 3rd gear. Would not go above 35 mph within about a mile of check engine light coming on. Had to be towed last three miles to service department. Oh, and tire pressure readings are reporting for the wrong sides of the car... Thankfully, bought the Gold Standard extended warranty. It has paid for itself, already.

Heard a loud clunk as car shifted into 2nd gear. Engine light came on immediately. Car took off slowly and would only go up to 40 mph b/c of high rpm. Drove directly to dealership and was told later that the wave plate was shattered.
