Transmission Leaks

[jpavone@vanstar.com]

The Ford Transmission on my 4/4 has a fairly "healthy" leak at the lowest
point of the bell housing (behind the sheet metal cover). I assume that its
comming from either the front seal or the one bolt which runs through the
bell housing and into the opening in the transmission.  What is the best
way to prevent the transmission oil from leaking through this bolt?   I
used a thread sealer which does not appear to be oil resistant. Thanks in
advance.

Regards,

John
