New transmission for 2WD XJ--what to do?

I have a 1996 Cherokee XJ, 2-wheel-drive, 4.0L with the Warner AW4 tranny. Just put an OME lift kit on it, Rubicon wheels, a new set of Wrangler Duratracs...

The transmission is leaking a lot of fluid from the rear output and I fear the bearings may be worn out, rather than just the seal and bushing.

I'm not opposed to just replacing the transmission with the same type--that would seem to be the easiest thing to do. But before I do anything I want to investigate whether there might be other feasible options.

My fantasy solution would be to convert to a manual transmission. Is there any manual transmission that would bolt on to the 4.0L engine? Or if I wanted to try to go that route, would I really just have to do a whole crate motor/ tranny?

If I were to consider a crate motor, where might I best look to find such a thing?

(I don't hate the AW4 transmission--even as an automatic, my Cherokee's been fun to drive. I do miss having a manual though.)

You won't what is wrong until you look inside. If necessary another AW-4 is the easiest and cheapest solution. The 4.0L was available with manual transmissions, but making the swap is not exactly what one might call simple.

According to the National Shooting Sports Foundation, AR-15 sporting rifles account for nearly 20% of all U.S. firearms sales.

Agreed, a transmission swap in a computer controlled vehicle usually required an entire doner vehicle to complete. Partially because you'll need a new PCM, petals, clutch hydraulics, and transmission.

Your swap is even more troublesome because you need a 2wd transmission to swap in.

If it were mine I would have a shop replace the output seal and flush the transmission.
