    Found this out for anyone who comes across this thread in the future.

    Engine Oil: 4wd With filter 5.5 qts Without filter 5.2 qts Dry Fill 6.2 qts

    Transmission: 5VZ-FE w/ 5 speed = 2.3 qts (but just fill until it comes out of the fill hole).

    Diffs:
    Front: 1.22 qts
    Rear w/o Diff Lock: 2.69 qts
    Rear w/Diff Lock: 3.18 qts

    For the transfer case, just fill until it starts spilling out. I'm guessing around 1.5 qts?

    Phew, that's 8.3 qts.

    I've heard really good things about Amsoil full synthetic and severe gear... it's kinda $$ but that's my plan when I get around to it.

    take the fill plugs out first... if you dump it and cant get the fill plugs out... On the aluminum cases dont over tighten the fill plug, it is tapered and there is the possibility of spliting the case, stripping the head or ...

    For the love of god do not reference the manual for gear oil quantities. There is a major typo for the 5 speed tranny... it says something absurd like 2.something quarts. It easily takes double that after draining. Sure, follow the manual for other stuff but I would buy 1 or two more quarts just in case.

    Tacoma is stock and staying that way, Pickup is TBA as of now.
    I always filled the diffs and t-case until oil came out. Don't use Delvac 1 in them, that's engine oil. Diesel engine oil to be specific.
