i have a 93 yj with a 4.0, ax 15, and np 231. i wanted to go auto and upgrade to a tuffer trans then the 32rh. did this swap for my wifes 73 cj5 258, 727, and dana 300 no adapters. i ran into a few snags on the way for my yj. There is no CPS (crank position sensor) on the 727. no big deal got a kit that moves the cps sensor to the harmonic balancer. 727 trans bolt pattern matches the 4.0. have to use a 258 flexplate to bolt to the 4.0 to the 727 transmission. got the lokar shifter and kickdown cable. the np 231 spline and bolt pattern matches the 727 transmission. only a 1" differance in length from the ax15 vs the 727. im good on everything EXCEPT: a bracket for the transfercase shifter and it looks like there is a pressed in collar in the crank where the pilot bearing goes. 1: do they make a bracket for the 727 and np231 shifter or do i need to fab one? 2: the collar in the crank; is there a tool to take it out? does it come out?
