They have seperate fill holes. You can use different oil in each but guys usually just do both in the event that the seal fails the oils wont contaminate eachother.

they are seperate. both diffs, tcase and the tranny all take gear oil (GL5, 80-90, 85-90 (check your manual)). All of these should have 2 big plugs (15/16") one is for filling and and one is for draining.

what is leaking (and where). As far as filling, just pull the fill (top) plug, get yourself a squeeze bottle and maybe a hose and fill er till she comes out. don't do this in your dad's garage...he'll get

Don't use 80w90! Use what Toyota recommends, 75W90. What difference does that little bit make, you ask. HUGE. I just filled my transmission with 80w90, and in the cold that transmission sucks! It's not as smooth as the recommended oil. So I changed it out immediately to Redline full synthetic 75w90. Wow. It's about $10 per quart, and you'll need about 3 quarts, but it's damn worth the $30. Good luck!
