I just put a tranny in a '13 1500 with 130k. I think that 6 speed chevy trans is the weak spot on that line.
Might have to cross over the dark side if they dont get it right.
My problem is they want me to cover the repair.
This seems like a powertrain problem that falls under warranty work to me.
But before I start getting crazy I want to make sure I'm not missing something.
2015 Silverado 2500 6.0 gasser
On a trip towing a trailer and a medium load. Check engine light comes on. No weird noise, still drives. I was tracking mileage for the trip and noticed I was 30% below usual mpg. Trans temp goes hot (275-285) and rpm jump to 4-5k to maintain highway speed...
