Thanks for the help everyone. I used the gray permatex stuff, but I think I paid $7 for the tube. Oh well. The transmission is in and works fine now. I think I have some sort of small oil leak around the back of it but that shouldn't be a big deal, either I'll fix it or just check the fluid often. Come to think of it, I don't think I tightened the drain plug since I wasn't the one who drained the fluid before it was sent to me, maybe thats all thats needed.
