Steve, I didn't realize you had sent me a PM until today. I thought I was supposed to get a pop-up notice when a PM came in, but I didn't get one this time. I have a new email address now, which I will PM to you. Thanks to the esteemed Mr. Snowden, I lost my nerdshack email. If you haven't heard the story behind that, just google "lavabit".

Anyway, I put GL1 in all of my manual transmissions when I can get it. When I couldn't find any I used straight 30 weight engine oil.

I bought a new SM326 with OD in 1966 and it came filled with ATF. The parts counter guy I bought it from (at a legitimate Chevy dealer) said it came from the St. Louis assembly plant and I thought it best not to ask any questions. Btw, that one DID have a drain plug.
