88\' Waggy to 90\' Wrangler swap?

I am thinking about pulling the axles, engine, t/c and tranny out of a 1988 G/Waggy and putting it in my 1990 Wrangler. Is this possible? The transmission is an auto, mine is ax-15. Is that a downgrade is performance? Any info is appreciated.

It should all fit just fine. You will need new driveshafts and 6- bolt wheels. The pitman arm will have to be drilled to accept the tie-rod end from the waggy. The TF727 will need a shifter, and a hole drilled for the Crank Position Sensor. You may also need a special flexplate to make the CPS work. I think you can get away without outboarding your front springs, but you will have to weld new perches on the rear axle. What else do you need to know?

Is the 727 a good auto tranny? Is auto good for crawling?

The 727 is a very good auto tranny. Much stonger than your AX15. Do some searches for auto vs manual posts, there are a bunch of them. I have a 727 in my Scrambler between my 258 and D300. There are driveshaft clearance issues on a CJ but your YJ should be fine because of the driver's drop front axle.

Also, the stuff I said about the Crank position sensor would only apply if you had a 4.0 since you have a 258 it isn't necessary. If you use the 360 everything will fit just like in the Grand Wag. You will just need new motor mounts and probably a different radiator.

Tom

What kind of t\c does the waggy have? Is it the np229? If so, inst that full time 4wd? Will that be a problem?

Probably has the NP229. You can just use the t-case from your YJ(NP231?) it should bolt right up to the 727.
