Gavin-

Several guys have rebuilt 722.3xx trannys, but nobody here currently has rebuilt a four-bolt and there's no write-up. I myself have rebuilt a Ford C-4 and I am in the (slow) process of stripping 3 parts trannies to try to make one good 722.315 for our 300D. It's not rocket science and is very educational ( as in....hmmm ...no wonder these things break)

You really don't need any special tools. A tranny jack IMO won't do much good because you can't get the car high enough with the tranny on board.

There is an ATSG service manual for the 722.1xx tranny. Consider it if you have the time.

Another option may be to find a car with a 722.1xx tranny in a u-pullit that was obviously running when it was hit or hit something. If nothing else, you can get some practice removing the unit on a junker.
