I recently went muddin w/ my stock cherokee... . Anyway Now it is not shifting until 4500 RPM and has a sparatic idle even dies sometimes. I know its not my tranny cause I checked it and it did'nt have any water in it, plus I had it flushed after these problems. I have a 4.0L I6 Auto tranny. If anyone has any suggestions as to what I can do to remedy this it would be greatly appreciated.
