My 2018 F250SD 6.2 with the  6R100 trans has a intermittent shudder in reverse, when backup up my 12K fifth wheel up driveway, that has about a 4 degree incline.. Many other owners of same combo on another forum have same issue with 2017-2018. Dealers have not been able to solve..  Putting in 4LO resolves issue, others had suspected parking brake sticking, hill descent control, but no real fix.

Any help appreciated

Does your truck have a conventional limited slip rear axle or does it have an e-locker? 

Does it "go away" in 4 high, or just 4 low? 

Do you have airbags on the rear axle?

Howdy

It has a e-locker rear axle, no air bags on axles.  I have not tried to duplicate in 4 high..The issue is intermittent, the same as others on https://www.ford-trucks.com/forums/  The trans fluid dipstick shows the fluid to look fine, and no burning smells. Its a 2018 built in May of 2018..

E-locker eliminates the chance of having limited slip chatter. 

If it stays in 4High but goes away in 4Low, its a trans/programming issue wherein the line pressure might be too low for low throttle input/high load or there may be an issue with the Direct or Low/Reverse clutch. If it is lessened or goes away in 4High, it is most likely a pinion angle issue with the extra loading of the suspension.
