I had a 2013 Silverado 1500 5.3 no problems at all, a 2014 Corvette 6.2, 7 speed manual, no problems at all.
My 2018 Sierra 6.2 with 8 speed shifted like crap and I sold it at 65,000 miles but no 6.2 problems at all.
My 2023 Silverado 1500 6.2 with 10 speed only has 30,000 on it. No motor issues, but the 10 speed is a whole new
experience. It will downshift when driving 35 – 50 MPH and won’t upshift. On the highway, flat roads towing my boat,
it will downshift motor is running 3400 RPMs, won’t upshift unless I let off the accelerator.
Dealer of course says it is fine, “the 10 speed is just shift happy”.
