Haaaard shift from 4-5

[kaptainkilo]

In sport mode this thing kicks the truck like it's being rear-ended. It seems to only be when going from 4th to 5th gear. Thoughts? Bone stock 2018 with 4500 miles.

Is this something theyll charge for if the truck is still under warranty?

Mine does the same thing. I’m hoping this will fix it.

The TSB will work. Before I had it done mine would sometimes chirp the tires going into 2 gear when I was barely on the throttle, then it would shift hard in some gears and rpm's would flare between other gear changes.
