OBDII AW4 to OBDI AW4

I've got a 93 cherokee that has a 4.0/AW4. The tranny is bad.... Can I swap a 98 AW4 (that's in my garage) into this Jeep?

I have heard there are different sensors and connectors but has anyone adapted them and made this work?

yup, done it myself. just use the old sensors and whatnot (ESPECIALLY the transmission speed sensor, the one with the 2 lobed...thing on the transmission output shaft) and it'll fire right up

I thought the output speed sensor change required a tailshaft conversion, which meant gutting the thing

old tranny in new jeep does, but new tranny in old jeep does not. the spinning lobe is keyed into the shaft the same way in both styles, and is held in with a snap ring in both styles. unfortunately, it seems that the new style lobe device is axially (height of ring) longer than the old one by just a hair. just remove the squared 4 lobe thing, and replace it with the rounded 2 lobe one, as well as swapping the pickup sensor. works beautifully for a combined 40,000ish miles for me.

Well, I got the rest of the story. Turns out the 93 Cherokee is a 93 Grand Cherokee with the 4.0 and the 42re transmission. I'm guessing the 98 AW4 won't swap into this setup.... Computers won't talk... correct?

Not trying to hi jack the thread but, since a 98 would work for a 93 can I put either one in my 89xj.

The output shaft on your 89 has a lower spline count so if you did it, you'd have to replace the transfer case input shaft.

I knew that and am planning on either an atlas II or a np241 4:1. Would all the connectors hook up and work correctly? What needs to be changed?
