I was hoping to avoid that route. And as of now I've been told that replacing the transmission won't fix anything and that it's a program issue. But no one will put that in writing or take any additional steps to correct the problem. Just frustrating. This is the first Chevy in a long time for me, wife has had nothing but Tahoe's (with no problems) and I have to say it will be the last Chevy, probably for a long time. I've never had to take a vehicle in for warranty work ever in my life until this truck and I've been driving for almost 30 years.
