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 38,400 miles by 2008 Acadia let me sitting on a busy roadway for 2 hours. After it was in the shop for 3 days, I was told they would have to rebuild my transmission. Great! Not very happy with this whole mess. I purchased this vehicle for daily use and also because I thought I could travel here and there for family vacations. Now I am afraid this will happen again. Just dissapointed in a car I loved. Rebuilt transmission with 38,000 miles. What next!

Driving along at 55mph on highway in cruise control, transmission slipped out of gear into like 3rd gear, limped it home 60 miles (real joy). Ran code reader on it P0700 and P0717. Reset codes, came right back 2 houses down. Read all the threads on-line, limped 8 miles over 2 hours to the dealer turning off car and restarting, erasing codes when that didn't work, wished I lived near tall bridge to throw this POS off of since this is our 3rd major issue after owning this SLT2 for less than 2 years! We were lucky enough to experience the water leaking sunroof and seam issues you can search on and the car has mold we can't get rid of. Wave plate shot and needs to be replaced. My super conservative Dad even is telling me to sell the POS the day I get it back and eat the loss and buy non-GM. Funny coming from a WWII vet who owned nothing but GM's over the past 60 years. GM is not the same as it was. I see a Honda in the near future.

Just informed of my wave plate being broken, to the tune of $2660+tax, and if debris in valve body, brand new transmission. Nothing like "quality" GM product. 62,000 miles is a little low to have this kind of problem.

our acadia will not go in reverse. my wife has to sit for at least 5 minutes before it will finally engage. what a piece of shit! if have spent at least 2k on this car since we purchased it 3 years ago. i will never buy another one of these cars again!!!
Car wasn't shifting properly. Broke down completely to a stand still (with my 3 kids in the car miles away from my home) and needed to be towed. Diagnosis from dealership: 3-5-R WAVE PLATE BROKEN. Transmission was repaired and reassembled. This seems to be a common problem with this vehicle. Class Action law suit??

First, loud noise coming from transmission, engine reving, no reverse. Dropped off @ dealership. Broken waveplate, trans needed rebuilt. When complete, a saturn outlook sitting outside with the same exact problem.I hope we're good now?

My 2008 Acadia with 62,000 miles required a re-built transmission. Two years later, at 84,000 miles the transmission is broken again. My warranty just expired 4 months ago, and I have had no response from the dealer other than "sorry", put in a new transmission for $4000

No reverse gear. At shop now.. Looks like a common problem with these acadias. Any recalls on this wave plate which appears to be faulty?
Having the same problems and noise
