  • Anyone convert the transmission fill plug ?

    The 17mm hex plug is a pain in the butt. Has anyone found a plug with an actual head so you are less likely to strip the thing ? Plus this would make it easier to remove. Thanks

    The E36 ZF 320 transmission drain plug has an external hex head on it.
    I think(90%) sure it is the same thread.

      Correct. I bought 2 plugs from an E36 M3 tranny to replace the OEM ones on the E30 after wasting 3+hrs getting a stripped OEM one of my rebuilt CR tranny....

      About $8/ea from the dealer a year or so ago.

        Thanks Guys - that brings up another question

        How do you get the transmission fill plug out ? My hex and breaker bar are too wide to get in there.

          You remove it very carefully! A friend of mine gave me a 17 mm hex socket that fit. Before that I used a dremel tool to cut down a 17 mm hand Allen key to fit and used a normal socket.

          I had more trouble with the drain plug after getting my rebuilt tranny back in.

            I bought new plugs and what I got were male (as opposed to female) I think they updated the design.

            To remove the old plug I hacked together a tool from a bolt and 2 nuts.

              BMW replaced the old style female with reaise male hex for the e30. Just ask for 2 e30 plugs at the dealer and you'll get what you want.
