Marty, you could use kerosine to clean your tranny. Just drain the old oil, put is a some kerosine and then run it for a little while to work it around in the tranny. Drain it, put in new 600 W oil and you should be good. Don't think it would be good to use kerosine in the rear end because like mentioned above, it may run into the brake drums. But if you just drain the rear end and refill it should work out OK.

Also like mentioned above, stop by and visit with Bert's. They can fix you up with just about everything you may need, both used and new stuff.
