All of the drain plugs on the 126 tranny pans I've seen feature a small round plug made out of metal. In the center of the plug, you should be able to fit a 5mm allen head wrench.

As was previously suggested, you may wish to remove it and replace the flat washer - available at local dealer. You'll drain approx. 3.5 qts of dexron and that's easily refilled thru the tube where you check the tranny fluid level under the hood. The actual amt. drained may depend on the previous content.
