I interpret that to mean fully to repaired with updated parts to prevent this in the future.

Yea, I got the same notice, I had to read it twice. It sure seems like double talk.

The way I interpret it - You (the customer) have an issue, we just wanted to let you know. We have a software update that will allow us to protect our best interest, but not address the root cause. The other issue You (the customer) have…we’re looking for a cheaper option, or simply kicking the can down the road. Don’t call us, we’ll call you.

Yeah, my letter for the 10 speed came yesterday. It’s definitely double talking jive.

Still doesn't answer the question, if we get this recall completed will this affect the TCM or regular tune? Also would a TCM tune make the "recall fix" think that it's shifting abnormally and throw the car into limp mode?

And, yes, I got my letter yesterday as well.

Appreciate everyone's point of view on this.

I have been burned by Chevrolet and GM on multiple occasions. I am aware of the time to resolve. But for me enough is enough. Time for them to be accountable. And like some of you I am also done with GM.

Ford has the same issue on their A6 trans but unlike GM. They are actually doing something about it.

Guess it is time to trade this thing in for a Supra.

It will absolutely affect the TCM

It reprograms the TCM with stock values + the software update to detect the issue.

Then if people like us reflash our proper tunes, what are we doing?

Erasing the previous tune, and uploading our own.

Thus no software lock out.

Or at the very least we have to have our cars retuned to be inclusive of the software lockout.

Has anyone had this actually happen to their transmission yet? I am just wondering how many Camaro’s in question have had this go bad.

Well my tuner who is on these forums, has one cooked A10, and is rebuilding a new one to handle the power. I did let him know about this recall and thread.

Have not heard back from him yet.

Updated video from 5 days ago: More stories of the Allison A10's take a shit.

What is significant about this is there is a story in here with a truck that had 2000-3000 miles on it when the wheel lock occured. I really want GM to explain how the software update will predict 10,000 miles before it happens.

Another sigificant story: One story with high mileage where the lock up occured, they installed the update, and the truck locked up again within 50 miles after the update. So ya, GM explain this one.

That said though I see you have a ZL1, someone here suggested you may not have the issue, I guess the ZL1's have the 10L90E transmission which is supposed to be different. I do not know enough to say for sure if that is the case. Also like your car mine is a 2020, Check your production date: Mine is Augst of 2019, so I'm on the recall, if your car predates April 2019 Then you should have a Gen 1 A10 which does not have the issue that we know of yet.

It may have gotten lost in the thread, or I may not have posted it, but I also got the recall notification in the mail.

Yea, that’s gotta suck. I’m just gonna keep going and hope that they will eventually do the right thing.

Ugh... I just pulled the trigger on kit valve body kit, including the shift solenoid valves. This is my keeper, so it just makes sense. I don't trust GM to do anything responsible about this situation, so it's up to me, IMO.

My aha moment was after the resonator cracked and GM would only replace with the OEM part, even though I brought along to the shop a x-over pipe that improved the design.

The resonator problem is a known issue and would just crack again from high temperatures.
I was thankful, we agreed with each other and I left to fix the problem.

If you DIY Next Gen's upgrade, after removing all of the bolts when the valve body is on the bench then flip the valve body over, then separate the halves to avoid all of the check balls falling out.

Take pictures and follow the Next Gen instructions. BTW, I have met with Next Gen to improve instructions which they said should be available next week.

However, the pictures in the previous post, should support you with the majority of ambiguity I encountered.

Discard the GM gaskets and replace with Next Gen's.

The retainers insert inside of the clips.
