Transmission Slip Out Of Gear problems of the 2010 Chevrolet Equinox

The transmission slips out of gear if the car does not reach 35 mph within the first two stops the car makes. When initially putting the car in drive, the car rocks back and forth while shifting into gear.

While approaching a stop at an intersection, my car slipped out of gear and began shaking and pulsing as I slowed to a stop. I pulled my car into an empty lot where I discovered I couldn't back up my car. It was towed to the dealer where they informed me the wave plate(35r plate) was damaged and would need to be replaced for a cost of $4,200. Service director at the dealer indicated that this was common in these types of transmissions and that there is no indication of when the failure might occur. Fortunately, I was traveling at a low rate of speed with no cars around me and was not involved in an accident, only left with a terribly expensive repair.

The contact owns a 2010 Chevrolet Equinox. While driving at approximately 20 mph, the vehicle failed to shift out of second gear and the check engine warning light illuminated. While the contact was driving home, the vehicle failed to shift into the reverse position. The vehicle was towed to a dealer. The technician diagnosed that the wave plates failed and the transmission needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 92,000.

Over the course of the past two years, the transmission steadily shifted harder and harder, sometime the gears wouldn't shift up, or down without a 3~5 second delay at speeds of 30mph or 50mph. Around Mar 18 2014, we were going up a hill going roughly 50mph all of a sudden, there was an external electrical noise, and seconds after, the car wouldn't shift into gear. After getting off the freeway, the car would not shift out of 1st gear, and was in limp mode. We took the car to the dealer the day after and was told the 3-5-reverse wave plate or also commonly referred to as clutch plate shattered and the pieces got into the gears and torn up all the gears with it. The car was still just right under the power train warranty so the dealer replaced the wave plate and the broken gears. But make no mistake, this is a common problem. Gm claimed they "supposedly" improved this old problem post 2009 models, however, countless 2010+ chevy Equinoxes, traverse, and GMC terrain, and acadia are still encountering failing transmission because of this very specific 3-5-reverse wave plate issue. Just google for "chevy Equinox transmission wave plate", or "gm 3 5 reverse wave plate" you'll see countless GMC, chevy 2010+ owners still encountering pre-mature transmission failures due to this very exact issue. If you take all the average transmission failures from all the 2010+ vehicles, you'll see that the transmission would fail on average anywhere between 60,000~150,000. This is not acceptable, and it should be listed as an official recall!!.
