Before you put in the transmission, have you measured the ID (inside diameter) of the old pilot bushing? If it is an AX15 transmission, they had two different sizes for two different input shafts on the jeep transmissions. Measure the ID with a caliper and then measure the input shaft OD (outside diameter). See is those two pieces match up. If they don't, you can buy the correct one you need from NOVAK Jeep Conversions on the internet. Removing the bushing is pretty simple BUT BEFORE YOU INSTALL THE NEW ONE (ASSUMING THIS IS YOUR PROBLEM), "trial fit" the new bushing on the input shaft to see if it fits first. Sometimes we can't sent the wrong bushing. If you have any problems with the removal of the bushing, so a search of this website and you will find out how.
