I have a 2021 F350 SRW with a 10-speed transmission. Shifts just fine when it is only the truck but add my 35-foot 5th wheel trailer and I have noticed that from being stopped like at a traffic signal, the light turns green...1st gear is smooth, 2nd shudders enough it can be felt in the steering, floor, seat, and this is not a jackrabbit start off the line, just normal acceleration. 3rd gear shudders about half as much then 4th gear on it is very smooth just like first gear. Anyone else experience this?
