21 to 23 spline conversation

[Wiggilez]

In my jeep I'm using a 1990 ax15 and a 1990 np242(from an auto trans). The ax15 has a 23 spline count where as my 242 only has 21. Can i grab an input from a 23 spline 231 and put it in my 242?

From a 91-94.5 t case. Yes u can

There was some gear pitch changes along the way,

way back when I swapped a 23 spline gear for a 21 spline (in a 231 box),

and the t-case sounded like it was full of rocks.

 

 

It could have been a 231 only thing,

just putting it out there that there was different generations of T-cases and not all of the gears interchange.

Yep. It changed in mid year 1994 That's why I said he need to find it from a 91-94.5 t case.

Get a matching tcase

Get a matching tcase

yep that's what I would do

cool thank you.

 

Get a matching tcase

 

I'd like to keep the 242 but they don't seem to be that common where I live, hell even finding an XJ in a JY is lucky.
