Be careful of moving on ... the 10 speed tranny can not be serviced yourself, dealer only, has no dipstick. Owners manual now $101 to buy has no info on trany, only "service if strenuously used". No info on fluid capacity, type, viscosity or filter type. Dealer charged $681 + tax, etc on 2020 3500hd diesel. Another ripoff deal from GM and Ford of shared design.
