Dadinator Posted December 29, 2012 Share Posted December 29, 2012 I think so, but not sure. As long as you get the transmission controller. (TCU) Not sure if a 93 would still have it or would be controlled by the ECU. If it has a TCU, it should work. Would be under the dash on the passenger side.

relyt120 Posted December 29, 2012 Share Posted December 29, 2012 Does 90 have mechanical speedo? That might also be an issue since the 93 definitely doesn't have a mechanical speedo. Link to comment Share on other sites More sharing options...

Eagle Posted December 29, 2012 Share Posted December 29, 2012 Mechanical speedo doesn't matter. The 93 will have a different spline count on the transfer case input shaft, so you can't swap over just the transfer case, you will have to swap the transmission and the transfer case together. But the 93 transfer case will work fine with the mechanical speedo cable. You'll have to retain the CPS from the 90, because the 93 Chrysler CPS doesn't work the same. You'll also need to retain the original 90 flex plate. The 93 transfer case doesn't have a vacuum port to control the front axle disconnect, but you'll be using the 93 front axle from the donor vehicle so that's a match-up. It should work.

Dadinator Posted December 30, 2012 Share Posted December 30, 2012 linkage for the transfer case and shifter. Front Driveshaft. You'll need a rear driveshaft, but obviously the XJ one won't work. All I can think of off the top. Link to comment Share on other sites More sharing options...
Eagle Posted December 30, 2012 Share Posted December 30, 2012 The rotors are calipers are different from yours, and yours won't fit the '93 axle. Be sure the front axle includes both the rotors and the calipers. Link to comment Share on other sites More sharing options...
comanche32 Posted December 31, 2012 Author Share Posted December 31, 2012 ok thanks alot guys for all the help and what would i do about the rear driveshaft. and anything you can think of I greatly appreciate it Link to comment Share on other sites More sharing options...
Dadinator Posted December 31, 2012 Share Posted December 31, 2012 I added about 2 inches to mine when I went from AW4 to AX15. I used a portion of my XJ donor's shaft. If you cannot fab, then you either have to find a drive shaft at the yard for your combo or have one made or modified. Link to comment Share on other sites More sharing options...
