i have an 87 yj eith a straight 6 and i was thinking of swaping the standard tranny with an auto with xcase and wondering if it will bolt on if the lengths would be the same my biggest problem is i cannot find a np231 21 spline xcase otherwise i would leave the standard in any info would be appreciated thanx

its alot harder to do standard to auto than auto to standard due to the wiring not being there so... thats the biggest issue. why you need a transfer case?

more info is needed, why you need to change trani etc
details man, details its all about the details..

the reason for the change is because our jeep does not have the trans case and we can not find a 21 spline np231 trans case so the only other option we have found is to take a transmission and trans case out of a cherokee.
