What Gear Lube For My Rebuilt Muncie

Hey guys,

I am very excited I just got back my newly rebuilt M-20 transmission for my 69 Camaro and it looks great. Completely new internals, case bead blasted, the works. The trans looks brand new. I won't be installing it for a month or so until the weather warms up.

Here is my question. I have always used 80W-90 gear lube and have never had a problem. Do you guys have a suggestions that may be better? I have heard a fair amount about synthetics both pros and cons and a fair amount about the GM syncromesh lube which is a mix of both. Or should I just stick with good old 80W-90?

What do you guys think?
