Taking front part of exhaust off makes it a lot easier, leave transfer case on if you have a trans jack, otherwise take it off, and be warned with transfer case off the trans is MASSIVELY FRONT HEAVY. Seen people jack from the middle and it just tips till it slams on the ground, the tc is very heavy and full of fluid, so make sure to support the front better and put a hand over the converter so it doesn't fall out as you pull the trans away from the flywheel.
Yeah, if you want to mess around with taking the torsion bar crossmember out, unloading the torsion bars, and make an extra 2 hours of work for yourself, leave the transfer case on. Otherwise, take the transfer case off first.
With the converter in, and the trans on a trans jack that is positioned in basically the center of the pan, the trans is almost perfectly balanced. I dont know how you can say its MASSIVELY FRONT HEAVY.....its not....... have the trans jack positioned/angled properly, dont be an idiot, and you wont have a problem. In fact, with the transfer case still on, it will be very TAIL heavy and want to tip backwards. Which is why I say DO NOT try to take the trans out as a whole assembly. Besides, you cant even get the whole thing out as one with the torsion bar crossmember in place anyways...as I said above.
When you take the converter out, the trans gets a little tail heavy, but not dangerously so.
run through all gears PRND321 waiting till you feel the pull, don't let it roll,
Why do you have to run it through "all the gears"? How is moving the shift lever to 3, 2, 1 is any different than just putting the shifter in drive?
