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.

Nick
