727 ASSEMBLY GREASE QUESTION

I used to work in a transmission rebuilding shop, on the Manual-trans and differential line. Every Fuller Roadranger kit comes with a small tube of Fuller silicone O-ring lube. Since the trans only has a couple of O-rings to lube, in the shifter mech. about 80/90 per cent of the tube is not used. I took the surplus tubes home until I amassed too many. That was in the late 70s.
I used the silicone-lube in every auto-trans I built, on the side.
I eventually ran out, and was forced to buy a small bottle, but Man! thatchit was pricey.
