My manual transmission rebuilder says not to use synthetic oil on the transmission; but I saw a thread suggesting Redline MT-80 which is a synthetic oil. It advertises to be used in manual transmissions.

I have an 883.
Listen to him....
Mineral base GL-4 (not GL-5) in SAE 80W-90, 90 or 140.
Since you're upstate (where?), 80W-90 will be fine. Unless you drive only in hot weather and do foot to the floor power shifts, SAE 140 is unnecessary.
Several choices at Summit, from cheap to expensive. Others available elsewhere.
Sta-Lube was recently a good option, but I'm not seeing it available at a reasonable price.

Over the counter 80W-90 as suggested for cooler climates, 140 for hotter climates or hard usage. I've never run the high name brand stuff because of the differences in pricing. I can buy the generic stuff at my local parts store much cheaper and it's never failed me.
In 68, in my 833 4 speed, Chrysler recommended auto transmission fluid which was type F back then.
