Leaking Drain Plug

[MH_Stevens]

A few weeks ago I posted regarding my needing to re-tap the drain plug thread on the tranny pan. Seems my treads are a bit too loose for the bolt and on a second oil change plug will not tighten up enough to seal washer and there is a slow leak. Until I can get a new pan is there a fix, a glue, a thread tape like plumbers use to hold the plug tight?

I'm surprised there is not a no thread plug available, like a rubber plug with a tightening screw but I have not been able to find one.

It's a plumbing item. Check your local hardware stores.

A couple of wraps of Teflon tape perhaps?

A new plug and some Locktight thread sealer and a soft washer did the trick. Just a note in case anyone picked up Mon photogoods advice - Teflon is dissolved by ATF.

you may need a new pan. Sometimes the threaded bung, which is spot-welded to the pan, breaks loose and that is why they leak. I have seen this on more than one 343 pan. I have not seen it on a 440 or 442 pan.

aHA! Yet ANOTHER reason the older tranny rules the roost!

...Teflon is dissolved by ATF.

Where did you pick up that? Teflon is very resistant to most solvents and hydrocarbons.

 

[MH_Stevens]

I didn't "pick it up". I found out when I tried it!

Your Teflon tape dissolved and turned into a liquid?

Went all slimy and sticky and was disolving.
