ive recently bought a 2015 Chevy, it currently has 5600 miles on it. The transmission has just recently started acting funny. It's constantly searching for a gear, especially when towing something. Shifts extremely hard, and sometimes the throttle response is awful, I'll have to completely take my foot off the gas and then accelerate again. My local dealer says the transmission is "learning my driving habits" and they have received many many complaints saying the same thing. The service tech I talked to literally said and I quote "we are aware of the problem but until gm realizes that there is a problem there's nothing we can do about it". He said until about 15,000 miles the truck will continue to do that until it learns my driving habits. But based from what I read online it does not get any better. Does anyone else have this problem?
