    Back to square one after the 2001. So...
    First, do you have your owner's manual? The specified grades/weights for your truck and condtions will be in there.

    The Amsoil manual tranny oil is the correct grade and spec. Synthetic is nice for the transmission. I use the Red Line synthetic GL4.

    I believe the tranfer case should take the same as the transmission, but I may be high and I don't have my manual handy. It's been about 10k miles since I did mine...

    For the diffs, it kinda depends. I think the maint. interval is 30k miles. But do you have the diff breather mod? If not, and you get into deeper water or mud and submerge the diffs, you'll need to change the oil anyway. In that case, I wouldn't bother with Amsoil synthetic, because it would be a waste of money. I just used Valvoline petro based. I think this is it:

    Oh, and welcome! Wow, post #1.

    agree with scocar. Trans and transfer are the same, sever gear 75-90, gl4. this may be beating a dead horse, never seem to get a clear answer, i hear gl5 can fuck up softer metals, anyway, yes. 2.3 and 1.2qt respectively i think. A word of advice, get the pump for that damn amsoil bottle for doing the trans, no room to get anything above the fill hole. 10 min job turned into a pain in the ass for me. ended up routing a 1/2 inch tube down thru engine bay into fill hole and filling it from there. I suck.
    I used castrol 80 90 hypoi gear oil for rear......dont know if it matters, everything i read said HYPOID was necessary

    And x2 on the redline MT-90

    You're correct on the GL-5 destroying the brass syncros. Stick with anything GL-4

    YES GET A PUMP! Especially for the front diff! And go get all the factory crush washers from Toyota. The tranny and transfer take the square-cut aluminum ones, the rear diff takes the steel crush washers top and bottom, and the front, oh shit, the bottom one is a big, special copper one, and I think the top is the same as the ones on the rear diff.

    If the rear diff plugs have not been off in a long time and were not torqued corrrectly or used the wrong crush washer, they can be a royal pain to get off. Start by taking the fill plug off. That way, you're not screwed with an empty diff and no way to refill it if you have issues getting the fill plug off.

    +1 definitely get the washers. Im a huge advocate of spending the 2$ to ensure you dont loose an oil plug and burn something up. Think of it like your paying $2 insurance on a $1000 part. A buddy used to talk shit because every time i changed oil in the motorcycle i used a new washer. He ended up loosing a plug on I 95. Didnt destroy the motor or crash, but he uses a new washer now. Not to say that the washer would prevent it totally, im sure there was a torque issue as well.

    Torque, rear dif...I think 36 and trans 27?

    The owner's manual (1999) says hypoid oil for the diffs. Can you NOT use a synthetic like RP in there? Are they not hypoid oils?

    In preparation for completing my swap to Amsoil, I visited my local stealership earlier today. scocar's descriptions are exactly right. Here are the part numbers:
    - Transmission = 2 x 90430-18008 ($1.51/ea)
    - Transfer Case = 2 x 90430-18008 ($1.51/ea)
    - Rear Differential = 2 x 12157-10010 ($1.23/ea)
    - Front Differential = 1 x 12157-10010 ($1.23) + 1 x 90430-24003 ($1.74)

    Total cost for this "insurance" was less than $13, including tax. :D
