My Jeep is still in good driving condition but it used to shift right down into 2nd at 45 mph and 1st around 25 i believe whem I put shifted down into 1st and 2nd gear on my jeep. Its a 1997 cherokee 4.0 with an automatic, it's lifted 5 inches with 33s. Now if im going 45 mph and i shift down to the 1st and 2nd it slips in and out of second and third. During summer I tried to rock myself out of a mud hole and kept going between drive and reverse at about 35 to 40 mph. Bad idea I know. Does anyone know what I can do to check whats wrong or have any ideas? It doesnt shift too very bad cause it still drives good but it slips a little now.
