Transfer case ?

Hey, I hae a 93 yj With the 4.0 And ax15 tranny. The tranny went out and I picked up an ax15 out of a 97. complete with external slave cylinder still connecetd to the master cylinder. My question is will this 97 ax15 bolt up to my 93 np231 transfercase? Someone was telling me the spline count on the output shaft of the 97's tranny might not be compatible with the 93 np321? I would sure like to know if this is gonna work before i get started lol. Thanks

You need to count the splines and measure the output shaft of the trans then to the same measurements on the input of the transfer case. If they match your good. If not well you know. You also need to measure the length since there were serveral different input/output lengths on these set ups.

I know the spline counts are different on the np231 between the 2.5 and 4.0. I do not believe the np231 is different (where it mates to the ax-15) between the YJ/TJ. Count the splines on the new transmission. I believe there are 23 on an AX-15.

You have to drop the xfer case anyway, so pull it and do a test fit with the new tranny.

The splines may not differ but there are 3 different ouput/input shaft sizes. You need to make sure those are the same as well.

Thanks guys

Hey thanks for the info. Looks like i will just have to take it out and look. lol. So Here is one more question. I want to go ahead and use the newer ax 15 with the external slave cylinder no matter what. But if i have to go with a newer np231 out of a tj. Does anybody know if it has the same mounting bracket locations. And same size yolks as the yj? Basicly do they have the same size ujoints ? Just wondering about possible modefications that might be needed between the 97 tj and my 93 yj. Thanks
