This just started today, and I'm getting a hard downshift from 5th to 4th when I have the exhaust brake on.
I usually drive around all the time with the brake on Auto.
I have no codes, and everything upshifts as normal, and all other gears are normal when downshifting.
It just seems to be that 5th to 4th.
Has anyone else experienced this before?
