    Good god....this is driving me crazy.

    What is the Toyota part number for the drain and fill plug gaskets for the manual transmission on a 2020 V6 6-speed manual TRD OR 4x4 (I'm sure most of that specific info doesn't matter....)?

    I'm going to lose my damn mind if I keep looking.

    Thank you.

    90430-A0003, but you really don’t need them. I’ve changed the fluid probably 4 or so times while reusing them.

    I haven’t replaced one, or had one leak in thirty years.

    The same washers are also used on the drain/fill plugs on the transfer case. You can get an aftermarket kit on Amazon that covers the diffs, MT, and transfer case.

    You'll also see a sticker on the fill plug telling you to check the manual before filling the MT since Toyota has used a different oil in the past for some MTs.
