Nwmo | I have a 2016 chevy with the same transmission engine as yours that wouldn't go out of 2nd gear on a couple of occasions within the first year. Took it to chevy dealer twice, they supposedly updated the transmission controller firmware. I haven't had any problems with it since. I will say it does seem to hang onto a gear longer than I think it should when pulling a trailer without have trailer mode turned on. I know of another guy that bought a 6 liter the same time I did and he went through the same thing. I heard horror stories about 15's and 16's shelling out transmissions, but mine hasn't so far. | |
