Transmission / Throttle

[ZR2Reaper]

Has anyone had any issues with the transmission? Truck seems to sputter under light acceleration then quickly has turned into hesitation and sputter between low speeds and high. No check engine light or codes at all but can definietly hear the whining and whirring coming from underneath upon take off. Planning on taking it to dealership tomorrow and test drive with tech. It’s almost as if it doesn’t want to go or figure out which gear to be in.

Haven't you heard? The 10 speed tranny's have a know valve body defect.

A little bit but more focused on the recall and didn’t realize it was potential for ours. Is it typical for that to be the issue with no check engine light or warning lights on the dash?

Thankfully, I have not experienced this but there are YouTube videos all over the internet related to the GM/FORD 10 speed tranny valve body problems. This may turn into a recall situation real soon

An experienced dealer tech told me last week the bad transmission valve bodies are a bigger issue than the motors and harder to get parts for them.

My transmissions seem to run great and I think they are well matched with tuning to the motor.

Just more bullshit quality control that leaves us wondering what's next. It's a damn shame for otherwise fun vehicles to drive.

I think I would have pulled over a lot sooner!

UPDATE: Torque converter was the culprit... 61K miles luckily under the CPO warranty

UPDATE AGAIN: Dealer threw in new torque converter and didn't fix it. Ended up being the valve body of course (my initial prediction). Anyone recently have any insight on the wait time I should expect? I know it is on a national backorder...

Ask them to contact GM and request the Next Gen Drivetrain Valve Body replacement kit...several folks have said GM has approved them to be ordered and Next Gen stated they have shipped hundreds to GM dealers across the country.

Is this at any cost to me if I request that?

I was told ZERO...GM picks up the entire cost.

I am going to reach out to them tomorrow and see what they say... will provide update. MTF

After two months parts were finally delivered to dealership, they stated it should be ready for pick-up tomorrow. This whole process has been a mess, and the lack of communication has been discouraging. If you are waiting on a valve body, I highly recommend you immediately start a case with GM customer care and have it elevated. After that call every two days asking for an update, for some reason no one will ever reach back out to you even when they say they will tp provide an update. Same goes for the dealership.

Glad you finnaly got it fixed.

Total CF orchestrated by GM.!
