Did a track day at Hallett on 1/17 and my M7 transmission failed. I ran seven 20 minute sessions and the transmission kept popping out of gear. It did it an average of 14 times per session! Put a big damper on the day and created a potentially dangerous situation.

I captured the transmission doing it on my PDR for all seven sessions. After throttle lift and braking was initiated it would pop out of third gear. This makes for a dangerous condition. When you're driving near the limit on track you need to be able to apply maintenance throttle through the apex to complete the corner. Makes for a scary situation when you go to apply maintenance throttle after braking and the car has constantly popped into neutral. Terrible.

I took the car to my dealer on Monday 1/19. Jim Glover Chevrolet in Tulsa is the dealer. The dealer has now had the car 8 days and GENERAL MOTORS won't even respond to my dealer's REPEATED requests on how to proceed. Eight days without my car and GM could care less. My dealer is as frustrated as I am.

I provided my dealer with video from two of the seven sessions and a written, detailed description of exactly what the car was doing. I even provided them the exact time mark on each of the videos where the car repeatedly popped out of gear 14 times each of the two sessions provided. I provided them everything they need to witness the failure and initiate a repair. If they were the least bit interested I could provide them video of the other 5 sessions.

I've been heavily involved in cars and racing many years. I and professionals I know who analyzed the car are quite certain the transmission needs at a minimum new syncro's and clutch hub gear. In a car this new GM needs to replace the transmission. I truly can't believe GM won't respond to my dealers request for fixing my car. Totally unacceptable.

FYI, this is NOT a shifter or linkage adjustment issue. I confirmed the shifter was properly centered the day I was at the track. There is no linkage to adjust on the Tremec TR-6070. I followed GM's service bulletin #PI1276A dated Sept 10, 2014, titled Difficult to Shift into Gear, Intermittent Gear Pop Out and/or Mushy Shifts (No Grind). My shifter was centered as specified.

I find it truly disappointing that Lawdogg got his engine replaced in 3 days but my dealer can't even get GM to show the slightest bit of interest. Eight days without a car and not a response from GM...

I won't drive it on the street as it is dangerous. If it pops out of gear when throttle is needed it could initiate an accident. I don't want to get hurt or hurt someone else.

GM's failure to address the issue or even respond to my dealer is incomprehensible and I'm without a car.

Yeah...that's pretty much unacceptable to handle a warranty claim like this by just not responding.
Good luck.

Sorry for your circumstance but do you think they might be asking why you continued to run it well after the first few times it popped out of gear? This might be the only reason I could suggest that they aren't responding just yet. I wonder if they are thinking you experienced a warranty problem but continued to push it??

Hope for the best.

Hummm...How sure are you that the dealer actually entered a claim for your tranny? Sometimes its the dealers who cause the delay and blame GM.

jim2527

Seriously...you drove a car with know mechanical issue on a track? Repeatedly?

Why?

i would take it back to the dealer and let it sit there and find out OK's lemon law process. if it's in your possession the clock on days down isn't running.

dvandentop

geez what a mess and yeah let the car sit at the dealer not your house. make it their problem. what is the dealer saying on no reply from gm? not sure why dealer level cant make the judgement calls on something like this

Unacceptable indeed...GM are you listening???

Hope this gets resolved in a favorable manner and soon.

Halltech

I would have them drop in an A8

Although GM should respond, it isn't in the business of sponsoring unofficial race programs thru its car warranty program. If that is how they view your activity at the race track, then perhaps they are carefully crafting a response denying any warranty claim.

try to find the regional rep for the dealership and see if he can help. If the dealership is not letting you contact him directly then its the dealership playing games.

TTRotary

GM should respond but I doubt they will cover your claim, since you provided documented information that you kept lapping despite an obvious issue. This should not have happened (the failure), but next time something like this happens (stuff breaks all the time in racing), please just pit the car. Better to be out the session cost than a transmission, or more importantly being the cause of an accident on the track. Either way this sucks and I sympathize.

Bummer, hope it all works out for you.

It's been sitting at the dealer for 8 days....

not sure I would have used track day video to document an issue but thats me.....good luck

Since GM is promoting this car for track use it's going to be interesting to see how they respond to this. With respect to driving the car after it popped out of gear several times, I agree it probably should not have continued to be driven, but it also should not have been popping out of gear in the first place.

dvandentop

i as well as many owners will be following this one closely

Call the GM regional rep yourself. squeaky wheel will get the grease. not say you should have to but I would call 5 times a day if I were in your situation. I had a syncro failure on my 08 z51 at 170miles and I contacted the regional rep to make sure they autorized a new tranny and I found them to be very helpful. they wanted the tranny back for an application engineer to inspect.

pewter99

yeah I was at the NCM when Dave Hill promoted the C6Z06 for track use...see where that got us
