Buick Enclave Transmission Fault and/or Check Engine Light With Code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723
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.
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? - Visitor
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? - Visitor
Iwas traveling on the ohio turnpike when my check engine light illuminated. It then started flashing that my transmission was overheating. I had to be towed 35 miles. The result was a new transmission at 59,000 miles.It would appear that the wave plate is the issue. The dealership did not know if the new transmission had the same faulty wave plate,or if a revised wave plate was installed. $4000.00 on the spot. It would appear a recall is in order. Very dangerous to be on the highway , and not able to go forward with trucks barreling down on you!! - Visitor
Transmission slipped once and engine light came on. Car would not exceed 40 MPH. - Visitor
I have the same problem with the wave plate issue, I encourage everyone to call the National Highway Traffic Safety Admin Vehicle Safety hotline 1-888-327-4236, they filed the complaint and will determine if an investigation is needed. Please call, maybe then we can get something done about this problem. Thanks, - Visitor

sudden loss of powerand prolongued gear shift in slow and go highway conditions. likely from 3-5th gear. Then within a week the car refused to go into reverse. 1 week for the repair at the dealership luckily uner warranty. no issues - Visitor
I just wanted to let everyone know that if you have had Wave plate issues, GM finally recalled it. I just received my notification this weekend April 2015. I paid $3495 for tear down and repair last year. I urge you to look into this and wish you luck. Because of sites like this, I took my complaint to GM when I had my issue. I felt it only fair to notify all of you that they finally recalled it. - Visitor
I've had 2008 Buick Enclave for 6 mths and chose not to get extended warranty. Vehicle slow going into reverse and drive. Sounds like car is idling too high RPM close to 4 when only going 40 miles hr and on interstate vehicle slowed to 30 miles hr... I thought I was going to be rear ended. High pitch whining, squealing sound. Check engine light come on and stayed on. I checked to make sure that I wasn't in low or had the emergency brake on neither was the case. Also happened 2 weeks ago and was told that I needed a battery which I brought at almost $200.00. In reading this is sounds like Buick/GMC should be responsible for repairing the damage caused by their faculty internal parts and have a recall issued on these vehicle for the safety of all. I'm regretting that I even bought this vehicle. - Visitor
Same as everyone else. It would not go into revese and whe n placed in drive the engine would rev up but not move. What a huge disappointment this car has been for what it cost. - Visitor
WHILE GETTING ON THE HIGHWAY, MY CAR STARTED TO HAVE TROUBLE SHIFTING GEARS... CHECK ENGINE LIGHT CAME ON, BROUGHT IT TO MECHANIC AND THEY CLEARED THE LIGHT, BUT THOUGHT IT MAY BE THE TRANSMISSION. TOLD ME TO DRIVE UNTIL ENGINE LIGHT COMES ON AGAIN WHICH I DID... NOW HAVE HAD TRANSMISSION REPLACED, BUT MECHANIC SAYS CARE STILL WILL NOT SHIFT PROPERLY. THIS WILL COST US 3600.00 AND ISN'T EVEN FIXED. I WENT ONLINE TO RESEARCH AND THERE ARE SO MANY MORE COMPLAINTS ABOUT THIS VEHICLE. GM SHOULD BE HELD ACCOUNTABLE FOR AT LEAST SOME OF THESE PROBLEMS. - threeforme61
2009 Buick Enclave AWD CXL Wave Plate failure. 24 days out of 5 year warranty. GM refused to cover the repair. Would only pay 60%. - Visitor
I've had this problem for more than a year. Had the Buick service mgr ride with me twice with the computer hooked up during drive. Never gets any codes to come up but you can feel the vibration when it tries to shift. Keep thinking it will eventually break. Then I will replace the trans with a factory rebuild. - Visitor
Transmission would not shift. Car running. Dealer recommended replacement of transmission at a cost of
$2600. - rcwalkup
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. - Visitor
Wave plate failure - Visitor
Wife noticed the extremely hard/lift shifting for certain gears, but the vehicle continued to operate. We had it in the shop the next day. They had to dismantle everything to confirm the issue was the wave spring. It was an rebuilt transmission was not available, so they had to rebuild this one. Nearly $3k for a $6 part. - Visitor
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. - Visitor
