The tranny has a drain plug like the oil pan except it's inverted (you'll need a 17mm hex key to loosen it). Instructions are on the <a href="http://20v.org/lubes.htm#trandiff">20v.org</a> website, but basically:

1. open fill plug before opening drain plug
2. drain old oil into suitable container
3. Use a funnel and plastic tube to route the oil into the filler hole and refill w/ 3 quarts GL-4 gear oil like Redline's MT90 (what I used)

You might as well do the rear differential while you're at it. It takes a GL-5 oil like Redline 75w90 (again, what I used). Same process, different oil.

HTH.
