Wonder why your transmissions shifts like it does? And why GM was telling dealers to tell customers the crappy shifting is normal?

Pay the piper GM!!!

ColoradoFans was all over this back in 2018. When I got my ‘18 ZR2, I had issues as well. Without ColoradoFans I wouldn’t have known how to get them taken care of. You could take it in with a very specific set of complaints and give them the associated TSB numbers and they’d take care of it. If not, they wouldn’t.

Even after the fixes, it still hunted gears pretty bad at highway speeds. A Trifecta tune that remapped both ECU and TCM took care of that. Completely changed the driving experience for the better.

It sucks when you have to go to those lengths to get a useable vehicle. :(
