stick to auto

I have a 89 short box MJ that I would like to put and auto in it. But I'm not to sure what I would have to do. It has a 4.0, the great france trans, and a killer 231. I want to keep the 231 and the 4.0 but get rid of the trans, and put and auto in it. I heard that the AW4 is a good one, but where can I find it, out of what year, and how will I know if it is and AW4? All the information will help! THANKS

The AW4 is a four-speed box found in 87-up XJ behind the 4.0. Pretty easy to spot - it's also the only light-duty automatic transmission that has an OEM drain plug. The sump pan is a regular rectangle, and has "Aisin" cast into the side in at least one place. I have one torn to bits in the garage, when I get a chance I'll take a look at the case and give you more ID tips.

The 2WD and 4WD versions are different - the tailshaft is different and the tailshaft housings are different, so watch for that. There are two different outputs as well - check www.advanceadapters.com for more info, as I know they have drawings there that are quite good.

If the output is different, the input on the NP231 can be swapped, relatively easily as I recall.

If you do the swap, I'd be interested in the clutch pedal and linkage, so let me know.

Also - make sure you get the TCU, and you will probably want the TPS from the donor (or get a replacement from OEMR) and the associated harness, as there is a significant different (the AT TCU for Renix does double duty, and has two outputs...)

Hey 444, I did this swap in my 89 XJ about 3 years ago........the are several "must do's" with this swap, as well as options. I have a good source for donor AW4 tranny's too. BTW, I sold my Pewgoat 5 speed for $400......guy that bought it was ready to pay almost $800+shipping for one in AZ.

I'll shoot you some more info on this later today........ I live in So Ogden, may see you on Saturday for the run up PC?

Where did you sell your Peugeot for $400? Ebay? Mine works perfectly, but I'm going to pull it sometime soon and put in an AW4.

Instead of messing with all the wiring on the AW4, I'm going to wire it up for full manual control.
