FireFighter32 Posted August 26, 2009 Share Posted August 26, 2009 Will a NP 231 out of a 1994 Cherokee that had an automatic bolt up to a AX-15 out of a 1994 Cherokee? Will the spline counts be the same? Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted August 26, 2009 Share Posted August 26, 2009 Will a NP 231 out of a 1994 Cherokee that had an automatic bolt up to a AX-15 out of a 1994 Cherokee? Will the spline counts be the same? I'm THINKING YOU TYPED THE WRONG DATES... BUT TO ANSWER YOUR QUESTION AS IT WAS ASKED, Nothing is set in stone as far as anything Jeep.. But YES, it should bolt up fine. CW Link to comment Share on other sites More sharing options...
FireFighter32 Posted August 26, 2009 Author Share Posted August 26, 2009 No the dates are right. I was given a 1994 Cherokee with an AX-15 and a NP231 as a parts Jeep. And I also have an NP 231 from another 1994 Cherokee that was an automatic. The Transfer case out of the manual Jeep has an SYE, where as the NP 231 out of the auto doesn't.

CWLONGSHOT Posted August 26, 2009 Share Posted August 26, 2009 Why would you think he typed the wrong dates? Cause its the same year. It's a fairly safe bet that same year will be same spline. Especially as we get into the mid 90's. The biggest spline counts changed with the remix/crico era. (21-23 spl, MOST of this was 1990) As parts where used up they where replaced with updated versions. That's why there is no set dates for changes and NOTHING is set in stone. What ever came out of the parts bin went on..... I thought he was going to come back with 84/94 XJ or some such thing..... CW Link to comment Share on other sites More sharing options...
mvusse Posted August 26, 2009 Share Posted August 26, 2009 If it doesn't work, and you're not afraid of getting dirty, you could always take the cases apart and move the SYE to the other case. Link to comment Share on other sites More sharing options...
Oizarod115 Posted August 26, 2009 Share Posted August 26, 2009 yes, by 94 ALL 4.0L stuff had a 23 spline t-case, only a 2.5 would have 21 spline by then. Link to comment Share on other sites More sharing options...
