Jerk or shudder

[devin]

My 10’ liberty seems to jerk or slip when accelerating sometimes, especially in wet weather or going up hill.. mostly I feel it on the free way going around 60mph. It’s seems to be right at a gear and goes back and forth between.

I used some of the transmission shudder fix and it seemed to help a bit..

any fixes?

Overdrive & Shifts are electronically controlled. You could take it in to a trans shop, to get the scanner connected, to see if there are any pending or set problem codes.
I'm not sure on the KK with an automatic, how much it likes to hunt between gears, so I'll let the KK owners elaborate.
Slipping on wet roads could be an issue with the tires breaking free during acceleration. What model/brand of tires/size do you have installed?
