Transmission Pan Screws -- 99 Elantra

    Hello,


    This past Saturday I was changing the transmission fluid on my sister's
    99 Elantra (3rd change with 97k). While tightening all of the screws that hold
    the transmission pan in, I ran into a problem with one of them which is longer
    than the other 12. I was hand tightening it and didn't feel any grip to it which
    seemed to be that the threads were stripped off. I then took the pan off and
    hand tightened the screw again and it held on without any problems.
    I then tried with the pan again but was only able to hand tighten it. Right now
    there are no leaks after 2 days (knock on wood), but I'm concerned that the
    screw is not holding. Does anyone know the length of this screw (HMA Service
    doesn't mention anything about the screw sizes, nor does it mention the 13th
    screw) and what pitch it has? I'm thinking of trying a just slightly longer
    screw to see if that helps.
    I know that the first time the transmission fluid was changed, it was
    changed by a dealer (which also left 2 of the splash guard screws off) but the
    second time was changed by myself, and I don't remember having any problems.


    Any advice would be greatly appreciated.

    All the screws are the same length from the factory. If one of them is
    longer now, it's because someone already stripped the hole and put in a
    longer screw so it would hold. You can try getting a screw that's just a
    little longer still, but if it's a blind hole, make sure you don't start
    trying to tighten beyond the bottom of the hole. In some places, this can
    damage fluid passages. If that doesn't work, the quick-fix (it's not
    pretty) is to get a 1/4" diameter screw instead and stuff into the hole.
    It's just a little bit bigger than the M6 that was there originally and
    isn't so big that it cannot cut it's own threads in the aluminum.
