    Tranny bolt?

    What is the pitch of the M12 bolts that are used to hold the tranny on the block

    ZF320 on a S50B30

    Thanks!

    M12x1.5 I believe. No way they're any finer than that.

    If you need a confirmation I can go down to my car and check.

      Realoem.com has the supplement listed for the transmission bolts.

        Real OEM state M12x90, which is the length...

        I called the dealer, and the guy told me that it was M12x1.75...

        That's what I bought.

        I had to buy the bolts today because I had borrowed a engine lift and I must give it back tonight. I will bolt my engine on my engine stand.
