1st gear is fine when in L, 2nd gear is ok unless pressure then it will slip, 3rd slips completley/wont go in gear, same with 4th and Reverse is gone!!!!! The shift kit worked fine for 2-3 months but failed about a week after getting the torque converter locked up. Could this me a pressure issue in the valve body ? I've been told that it the sprag on the input shaft into the gearbox. My automechanic wants to put a new box in but i have suspicions its may be just the valve body that has failed or springs have collapsed not closing valves
when they shift kited the valve body they dis-abled the torque converter lockup and was reving at 3k at 100km on the freeway, got it locked up again and idled at 2200 at 100km
