I have a 94 YJ... My 4cyl blew out and I'm getting ready to rebuild a 4.0 from a 90 XJ. I'm trying to get info about AX-15 Transmissions. Would like to know if I can use one out of a 94YJ or would it be better to try to find one out of an 90 XJ and just swap out the tail end? The Ax-15 are hard to find out of an XJ is my problem. Any info is greatly appreciated. Thank you for your time.
