I have an 04 Renegade with 103000 miles on it. I recently had an "overhaul" and a shift kit done to the tranny. Does great in 2wd, but when I shift into 4low, the tranny slips when I start giving it gas is drive or reverse. Works fine once I get going until I have to stop and turn around. Starts slipping again. Then if I go back in to 4hi or 2wd I have a total loss of power. Almost like its trying to start in 2nd. So I turn it off and restart and it seems to run fine, but then the check engine light comes on. P0700-tranny code. So I do what anybody else would do and disconnect the battery.
All is fine until I go wheeling and put it 4low, then its starts all over. This has happened many times. I am tired of disconnecting the battery, so I am taking it back in. Anybody know what's going on or have the same issues? I would like to know so when I take it back, I'll sound like I know what I'm talking about.
