    Hi Guys.
    Are the rear engine plates (plate that goes between the engine and transmission) a 2 piece item, A full one and a half one at the top?
    I have the manual transmission out of my car at the moment and it has only ever had the full one fitted, should it have other half?
    I have looked through the service manual - and can only find a reference to the half plate which the call "rear plate"

    Are the manual and auto engine plates the same?

    Thanks.
    Col

    Yeah.
    I’ve got 2 full plates and 2 half plates (from bits and pieces collected over the years)
    The witness marks arnt really telling me much of a story as to how they are fitted

    The auto having 2 half plates makes sense, bottom one removed to access the torque converter bolts.
    Can you take pics of those for me?
    I’m going to need that for my auto car
    Cheers

    The full plate is for manual trans. They will only fit one way.

    Thanks guys.
    I don’t have that bottom filler peice for my manual, I assume it’s there to keep out as much dust etc as possible.
    Has anyone got pics of an automatic set up?
    Or is it as simple as the manual one cut in half so the torque converter bolts can be accessible, and they use the dust cover bit as well?
    Cheers

    It's also to fill the gap between the gearbox and engine.

    Without it you may end up cracking the alloy housing on the gearbox when torqueing the bolts up?

    You can run without one altogether if you need to.

    I’m not saying do or don’t, but plenty do.

    I’m hearing ya.
    Measuring it up in regard to the required clearances for the torque converter, it looks like I should use one.
    I might just cut a manual plate in half so I can remove the bottom section to get access to the converter bolts.

    I think I have too, well it looks like half a full manual plate, so I guess it is, just don’t have the bottom half
