    Time for front and rear differential, transfer case and manual transmission gear oil change on my 00 Tacoma. Looking in my owners manual I see 75W-90 GL4 or GL5 recommended. Rear diff says 90 weight above zero or 80w or 80w-90 below zero. Anyone use 75w-90 in everything. Any particular brand? Synthetic or dino oil?

    I use Lucas synthetic 75w-90 in both diffs and the transfer case, works great. Can’t speak to the manual transmission from personal experience, but most people recommend Redline MT-90.

    I did MT90 in my MT a few weeks ago and I think it definitely shifts better, getting into first was a rough spot and its easy now.


    If you're doing both tcase and transmission, consider removing the shifters and filling them from the top, and maybe do the shifter bushing on the MT while you're in there. Just be prepared to re-seal when you're done, I tried reusing the gasket and that went poorly.

    Undo fill plugs first, then undo drain.

    This is in case you fuck up the fill plug yet already removed the drain plug.

    Also, if you want to do away with the hex plugs on your front diff altogether;

    Front diff fill plug replacement 90341-18060
    Front diff drain plug replacement 90341-24016

    This will give you a metric bolt head.

    I did swap over from Amsoil 75W-90 GL-5 to Redline MT-90 GL-4 in the R150F 5 speed manual transmission. The Redline MT-90 made a very noticeable positive difference in the function of the synchro rings in the gear box and lowered the noise level of the bearings which appear to be (sound) worn. Will continue to use Amsoil 75W-90 GL-5 in the front and rear diffs but am sold on MT-90 GL-4 use in the gear box. .02

    I really liked the Valvoline in a bag. The bag is flexible so you don’t need a pump, and they are cheap and available at Walmart.

    I did 80W90 in the rear diff and 75W90 in the T-case and front diff. This is what the manual specifies so I just followed up.

    Hey this is an awesome looking service kit. Do you know why they offer 2 front diff drain and 2 front diff fill etc? Is it just so you have extras?

    Thanks
