Problem Description and Possible Solution
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.

Last week my transmission failed on my 09 Malibu. "No Reverse/ 3rd or 5th Gear, DTC P0776". I am 10 months out of power train warranty. GM has been contacted and may or may not assist with a partial payment of the repair cost. Any suggestions on how to approach this matter further.
Wont shift out of first gear and shows a check engine icon. I checked OBD tool and had two fault codes P0700 and P0717
My car was driving good than all of a sudden it wouldn't reverse... I'm confused cause I'm 8months pregnant and needs a rode to my appointments. My car also has a recall on it ..so do the dealer have to pay for this or I do cause I need to know.
My car goes in reverse and does not go forward. The opposite but seem like the same issues.
Car was fine, parked it in the driveway.Next time I tried to use it, it wouldn't go in reverse.Then other gears went. Very upset. Looks like this is an ongoing problem costing loyal customers alot of money. Is GM doing anything to help?
Reverse is out, slips shifting gears and makes a whining noise.
No reverse. Trans needed to be rebuilt. Main shaft badly scored needing replacing. NO TRANS DIP STICK FROM FACTORY TO SHOW FLUID LEVEL. Wave plate broken in three pieces. Fluid dark and burned looking. Repairman stated this is an ongoing problem with the General Motors 6-speed automatic transmissions.
Vehicle wouldn't shift out of 3rd gear and RPMs were very high. Dealer said that the wave plate broke and damaged the speed sensor. They wanted $2100 to replace both. I was upset and said I was going to take it somewhere else. Then they said $1100 to do the repair with a used wave plate. The part new only costs $20. I hate GM products and the customer service is terrible. They were willing to take $1000 off and say they could do that if they used an old part. That makes no sense when its an inexpenisve part even when bought new. My research revealed that the Chinese wave plate used in the late 2000's is faulty and explodes once it gets brittle from heat. Why no recall? Don't buy GM. I'm still arguing with the dealer about this.
Same issue. Faulty wave plate. GM needs to stand up and take care of this for their loyal owners. Im very disappointed and will not buy another. Ive owned 2 Toyotas and never had a tranny issue.
Vehicle started jerking and RPMs all over. Car would not reverse. Mechanic found it had no reverse, no first gear, lots of noise in second gear. Transmission failed. There were NO check engine lights on however transmission shop pulled the following codes p0621, p0700, p0776, b1325, u0155. They determined that the wave plate broke and the broken pieces fell into the planetary gear set causing damage to that. They replaced wave plate, planetary gear set, and torque converter, overhaul of transmission. Cost just under $3000. Transmission shop contacted GM to make sure there was no recall due to low mileage on vehicle and that it was well taken care of.....GM stated they are aware of the issue and are "close" to issuing a recall. I don't want to hold my breath on that but I would love a refund. GM customer service is terrible and will never buy another vehicle from them. The shop also told me that an SUV by GM which has the same transmission (only larger) had same problems and had already been recalled.
Driving down the road at 20mph and the transmission started slipping. Pulled over a block later. No reverse and will only go into 1st gear. Turns out the wave plate is broken and I'll need to replace the entire transmission due to metal debris that went into the transmission. I bought the car at 72000mi and never made it to my 1st oil change. Thanks GM. I've been a loyal Chevy owner since 1999, but this will be the last one I ever buy!
Started car, check engine illuminated then wouldn't shift out of first gear.
Clutch wave plate won't go In reverse
Transmission got stuck in the 1 st gear and check engine light came on after tri to the gas station it has been slipping 2 and 3 shift for few months. Vehicle under warranty towed to the dealer who determined wave plate needs to be replaced. Dealer is currently working on in, should be repaired in couple days.
I just bought my car 2 and a half months ago and now the car won shift in to first or reverse.
the problem has not been fixed I just purchased the care and thats the first thing I noticed it jerked really bad when changing gears and it was hard to get out of park and the lights do not show up
Loss of reverse wave plate replacement necessary wait to here from GM on replacement assistance.
check engine light went on and unable to put car in reverse...vehicle towed to dealer...broken wave plate...transmission may or may not have to be replaced.....
Transmission would slip or have trouble shifting out of 3rd or 5th gear. Dealer offered either replacement of affected parts including the wave plate in the transmission or a completely rebuilt transmission from the factory.
3 5 reverse wave plate failed at 58 miles out of warranty. Dealer only wants to give me 25% off repairs, under the GM Goodwill Policy, because the 5 year portion of the warranty is over by 262 days. Bought the car new in August of 2010, and have had 18 oil changes and couple of tire rotations at this same dealer. It,s a transmission problem. The transmission does not wear and tear while parked. I think the definition of Powertrain is = what make the car go! Any one have success with GM covering this obvious defect. They extended the warranty on the 2009 malibu (service Bulliten #14404) Find it hard to believe that those same transmissions were not used in some or all of the 2010's. I'm saying, surely they did not just throw them all away?
