    tranny oil plug gasket size

    Is the gasket/washer size the same for both the engine oil plug and tranny oil plug? Anyone knows? I know it's M20 for engine, but not sure about the transmission plug. Thanks.

    It's not the same size. The tranny washer doesn't appear to be a crush style washer like the oil drain plug so it looks reusable. I don't know the size of the tranny plug but it is a larger diameter than the oil plug.

    The tranny plug is 21mm. It has a permanent metal washer around it. No crush washer.
