I have an 05 Cherokee with the 944 code, vehicle doesn't move in reverse at all and third works only when the rpm's are bumped up. I changed the filter and fluid as per tsb but still nothing. Any other ideas?
Thanks -
Was there any debris on the pan? At this point the next step is to check foe transmission fluid pressures. I recommend having a transmission shop check that for you.
