I oiled the bearings liberally with transmission fluid before installing them. I also used Red Transjel to stick them into their respective places in order to keep the orientation straight. It helped that they only wanted to sit flush one way, and they're oriented the same way as each other. Even though I checked twice, I may pull the overdrive assembly apart again because I'm second guessing myself.

I will be taking both measurements, for both of the shims, tomorrow.

Oh, the seal on the back of the 4wd overdrive housing, should I install it with the opening (the side with the spring in it) toward the transfer case or back facing the overdrive internals?

Also, are the 22 degree angled gears appropriate for a gas application? This transmission is going behind a 5.9L Magnum.

Thank you for putting up with all of this new guy's questions. I couldn't find straight answers to these questions anywhere. Not in the FSM, the ATSG book, or in other forums.
