I was braking to a stop light, I hear some nasty noise and the transmission thuds, then all of a sudden it only works in reverse. I have BNR tune, magnaflow catback, eibach springs, catless downpipe(could put back on the stock one) which none of them should have caused an issue, I also wasn’t even pushing the car just simply making a roadtrip to pick up a stranded friend

I imagine it would be....

really praying it is, you think it would be even with the tune? thats the only thing i could imagine causing them to deny a warranty claim

Yes the Tune could be very problematic. I'd restore everything to stock before attempting help

I THINK we have a 100,000 mile drivetrain warranty. (Yes? No?) But if you modify anything (like you have) restore it to stock or else GM will absolutely refuse.
Next possible problem even if you restore everything to stock...will the computer remember the modification?

Let us know what happens.

You are under 60,000 miles, so I would think so.

This is why my next new to me vehicle will probably be a CPO vehicle. Check out the CPO warranty on Ford and GM vehicles in particular.

Agreed. The tune is grounds to void your powertrain warranty if the dealer wants too. More than factory designed power WILL shorten the life of the stock powertrain. By how much? That's the million dollar question.

wish I could restore it to stock but the car is sitting 300 miles away still waiting to be towed to a dealership there, sounds like the warranty is out of the question then

BNR also increases the pressure on the solenoids and it shifts harder/faster. Definitely voided. Now you could un flash it before you take it in. I am not saying to, but I am not saying not to.

Hopefully BNR made the tune so it wouldn't incrimate the flash counter. Actually I'm not even sure if the ECM and TCM have flash counters??

I am told dealers can’t see tunes. But who knows. I am sure they could if they really wanted to.

Report back if they will warranty it.

Is not driving the 600 mile round trip not worth the cost of a new trans?

GM, a 100,000-mile warranty? You are thinking about a company that fully stands behind their product, GM stopped that in 2016

the car isn’t abandoned my insurance company had it towed this morning to the dealership near there, plus I have no other vehicles at my disposal

Isn't the warranty is 100K on CPO vehicles?

What good will that do? If it’s warranty they will scan the computer and see it was tampered with.

So you have proof it works that way? I’ve been told otherwise.

When I asked fleece for a diesel tune when they where open I asked if GM had any way of knowing it was flashed. They said yes they can tell.

You could be eligible for a Rental Car

I didn't read anywhere in this post this Car was a CPO Car which now offers more extended coverage than previously. Of course a CPO Car also costs more?
Each Chevrolet CPO vehicle is thoroughly inspected and reconditioned before you buy it. And when you pull off the lot, you’ll have your own happily ever after with a Scheduled Maintenance Program† and two factory-backed warranties: a new, longer 6-Year/100,000-Mile Powertrain Limited Warranty (whichever comes first, from original in-service date)† that includes Roadside Assistance,† and a 12-Month/12,000-Mile† Bumper-to-Bumper Limited Warranty.
