    Default A/T Pan Fill Copper Washer Size is... what?

    Leaking from that fill plug, reused the copper washer and now she's got the drips.....

    Tranny is the A/T by General Motors THM R1 (aka BMW A4A 310R.)

    Anyone know the internal and external diameter for that washer?

    Can't bear to pull the plug, get the washer, fluid drains out... go to store to LOOK for a new washer (if they have one)... etc etc....

    If I had the size I'd just get it ahead of time....

    What else can I do? Don't want to use RTV... already cranked it real snug.. anymore and it may break something...

    THANK YOU. -Rob.

    Default RealOEM shows the part....

    ..but not the size.... nearest dealer is 60 miles away, so if I just knew the size i'd be good to go....

    thank you. may just get the filter kit.

    Best might be to call your dealer and hope for a friendly service there which tells you the size.

    I'm reasonably confident it's a 14mm bolt so a seal ring with that ID and prob 17mmOD.
