CTswampyankee Posted January 21, 2011 Share Posted January 21, 2011 I'm soon going to be swapping my 88 2wd to 4x4. Its currently a renix 4.0 an 2wd AW4. I plan on using my 90 renix 4.0 compleat drive train. But my donor is a 90 with a ax15 tranny. I would like to keep my swaped truck a auto aw4. What year trannys will work with my current 1988 wiring? I do know the renix has a bell housing CPS. Is it as easy as swaping on the renix 87-90 bell housing on any AW4?

Eagle Posted January 22, 2011 Share Posted January 22, 2011 You're going to need a 4WD AW4, and they usually come with the bellhousing attached. Link to comment Share on other sites More sharing options...
carnuck Posted January 25, 2011 Share Posted January 25, 2011 If you get a 4 cyl one ('87 up), you can swap the 6 cyl bell, but it's not quite as strong. Get a matching pair trans/tcase from '87 to '96 and they will work. Mismatching means you need 21 spline to '90 and 23 spline '91 up on the 6 cyls.

CTswampyankee Posted January 25, 2011 Author Share Posted January 25, 2011 The wiring is all the same? I know my 88 jeep has a aw4 currenty, with the power an econn switch on the dash. Link to comment Share on other sites More sharing options...
carnuck Posted January 29, 2011 Share Posted January 29, 2011 That just controls the computer. You can even wire up newer AW4s to run like that (program is already in them. Just the wires weren't included) Link to comment Share on other sites More sharing options...
