It might not be broke but once you get it wheeling you can almost guerentee it will. I say don't waste any time cleaning up that tranny and get something with a good first gear and significantly stronger. look for any 4 speed out of a pickup and you will be good to go.
Sorry to get off topic but I have a personal thing with those tranny's lets just say I keep a few SAE wrenches in my foreign rig everytime I wheel with one of those or the lesser jeep tranny's, and I've had to break them out more then once.
