jimoshel Posted July 20, 2011 Share Posted July 20, 2011 Checked search with no results. '89 XJ, MJ, Will a 231 trans case swap between a standard and auto trans? Link to comment Share on other sites More sharing options...
Geonovast Posted July 20, 2011 Share Posted July 20, 2011 That depends. If you're talking the BA 10/5, yes, they should. The AW-4 was still 21 spline at that point. If you're talking AX-15, no, it won't as the AX-15 was 23 spline. You can swap the input shafts, if the cases are from the same generation... the pitch on the reduction gears was changed a few times, not sure on when that happened. The AX-4/5 was 21 spline, but it used a long input on the T-case. Link to comment Share on other sites More sharing options...
Garvin Posted July 20, 2011 Share Posted July 20, 2011 Mid '94 was the change in pitch. I used an early '94 NP242 input in my '90 NP231 transfer case without an issue. Link to comment Share on other sites More sharing options...
