Just started happening, 2020 model, a little over 56k miles. Upon decel from 50-60 mph it will do this weird abrupt jerk once it slows down to around 30mph.

I'm thinking maybe the transmission may need a flush or something because I assume it's a downshift point but not sure.

Has anyone else experienced this?

I usually have a little abrupt shift at that speed when it up shifts in sport mode, but if it is a jerk and is not in sport mode probably needs a transmission flush.

A jerk you say?



In all seriousness, I know there is a skip-gear shift, I wonder if that's the one? :unsure:
(Hooray things we do for fuel economy! Why have so many gears if you're not going to use them? Beats the he** out of me)

Sport mode goes through all the gears. Normal and Eco skip gears up shifting and downshifting. Raptor does the same thing. To me it gives it a lazy tranny response , and I agree I would rather have it not do that.

If it's an abrupt 6-7th gear upshift or downshift, then it's what I had at 25K miles which required a TSB to rebuild it something about the A-clutch clamp or braket.
