zagscrawler Posted November 9, 2011 Share Posted November 9, 2011 Well it looks like I'm going to be swapping out this old @$$ ba10 trans for an Aw4 after all.. Anyone have any suggestions as to a good year and any other info on a solid auto trans? Ive got a 88 2wd I'm converting to 4wd. Thanks all Link to comment Share on other sites More sharing options...
Dadinator Posted November 9, 2011 Share Posted November 9, 2011 I've got one I'll sell you with and NP231 attached already and a spare NP231. I'll include the control module. $175 + Shipping. It's covered with oil and gunk as my truck used to leak from everywhere. It shifted good when I pulled it. Converted to manual. Let me know. Mike.

HOrnbrod Posted November 10, 2011 Share Posted November 10, 2011 If you are converting a 88 2WD to auto/4WD, I'd go with a 91 XJ/MJ and up donor as the AW4s changed from 21 to 23 spline inputs in 91. Or was it 1990? :hmm: Not a big deal depending on how you will be using it, but the 23-spline is more robust and will allow you to utilize the later model t-cases.

mvusse Posted November 10, 2011 Share Posted November 10, 2011 I abuse my 87 mercilessly about once a month with 35" tires and dual lockers. The 21 spline output on the transmission has never once been an issue yet. I have grenaded front u joints, busted front axle shafts, broken a front driveshaft at the double cardan joint and twisted a rear driveshaft in half, but the transmission/transfer case have been fine. $175 with transfer case attached plus a spare case is a good deal.

Congrats on getting married this Friday! :clapping: I also have the front shaft and a front axle as well I'll sell cheap. (3.07:1) Linkage, the whole nine yards. I'm parting out a 1990 XJ if you need anything... Link to comment Share on other sites More sharing options...
