Removing transmission Drain Plugs, heat? Options

[Jon H.]

I have my transmission apart on the bench and I can't get the drain plug out? I'm not sure if I should use heat or not; out of fear of melting the case? What do you guys think? A little heat with the propane or get glowing with the oxy?

Thanks' Jon

I have not seen any of the external 911/914-6 plugs for sale. Do you know a source?

Mine just came attached to the cars.
Always figured it was a dealer item.

Stoddard has a 999-064-020-02 magnetic drain plug for $16, which they say fits 519, 644, 716, and 741 transmissions - but they're the 356 specialists. That's the part number for 911 from the PET. No description tho.

Pelican has the same part number, but they do describe it as a 17mm internal hex, even though they show the same range of applications ('65-'89 911, 914).

Since it's a 999 number Porsche considered it 'general supply' so the 19mm external hex parts may just have been what was available off the shelf in the early '70's.

I expect there's a stash of them somewhere, possibly with someone who does a lot of 911 transmissions - Gary Fairbanks?

So - I didn't mean to set someone off on a wild goose chase, just thought it'd be a dealer item.
