If the tranny is shifting hard it is probalby not the fluid. Low fluid usually makes it have funny, slow, or late shifts.

What was wrong with the transfer case???? If it is a 208, I don't know how you broke it. My case has alot of abuse and alot of miles. The only problem is if you hit the case on a rock, or if you don't have enough of the slip yoke engaged on the splines.
