For the top nut, you need

1. One flexible ratchet, Sears variety, 10 inch long
2. One 6 inch long 10mm Allen bit in a socket. Would be much better if it has a round ball at the end so it can flex a little and still bites. I had to make my own tool here by cutting off the bit and epoxying it to a 10 mm socket.

Hug the tranny, come from the top, fit in the 6 inch long socket and flex ratchet, and turn.
