I've gotten sucked into this debate before. General opinion was they should use ATF. I've always (since the mid 70's) used 80W90 gear oil. Have never had a problem with it, even in cold weather driving, which is where I think the ATF discussion originated from. Purely my own opinion and experience.
Lead, follow or get the hell out of the way

Anyone have any recommendations as to the type of lube to use in my 4 speed tranny? We've heard some say synthetic and others not. Any opinions?
80w-90...end of story IMHO

Waaay back when, I had a '66 Formula S, 4spd. Lived in Vermont. In the cold of the first winter I had it (used) I would go out to start it and let it warm up. Push clutch, start engine. Let clutch out, it would stall the engine. Had to rev it up, ease out the clutch. I checked around, then drained it and put dexron in. End of problem. I "believe" all the other four speeders that I had were factory filled with dexron. The 4 gear in my VL21 will have 80/90 if it ever gets on the road, now that I live in Fla.
It takes gasoline to interest me.

I fully agree with the 80w-90. Also make sure it is GL-4 Rated NOT GL-5. GL-5 has too many friction modifiers in it and will not let the syncro grab the hub enough to slow the gear down. GL-5 is made for rear ends.

In this thread I have read the downside or possible downside to ATF and Synthetics, so why chance it? No one has mentioned a downside to 80w90 except maybe the cold weather. I have always used gear oil but I cant say I have had any with original fluid and of course most if not all have been from down here.
Careful, your character's showing!
