My 2020 Trail Boss is in the shop right now. It's been in the shop for almost 2 weeks and the dealer is backed up so they haven't fully diagnosed it yet. Truck has 12, 615 miles on it. The tranny went all of a sudden. Left the house one morning, stopped a stoplight and when I took off from the light the check engine light came on and the truck started jerking. RPMs were up around 3800 and the transmission was slipping. Drove to the dealer and they checked the code, thinking at first it was a computer glitch or valve body issue. Because they were so backed up I decided to have them reset the code and drive it for a while to see if it would reoccur. 10 mins later the same thing happened. RPMs were around 4k at 70 mph and when I pulled away from a stop it would take 30 seconds or so for the tranny to engage enough to build up driving speed. Just posting for awareness and curious if anyone else has had problems with the 10 speed. I drive the truck about 6k miles a year and do not pull a trailer.
