Transmission Lube

[plateaucal]

Just wondering what kind of gear lube folks are running in the tranny and transfer case. Weight, brand, etc. Is the 85-140 too heavy? Thanks in advance.

Hi mate, for my old 1966 G60, I Just Run 80-90 Penrite Gear Oil, That's what I Recommend and I think its the Viscosity that should be used, Hope that Helps, cheers Mike

Thanks for the reply. I ran so heavier stuff in the transfer, just to see how it goes, but I think I will stick with the 80-90 in the tranny.
