Hey,
I need help choosing the right transmissoin and gerabox oils for my 1957 Chevy.

It has manual 4 tranny and 1:4.11 gear box (GM 10 bolt).

Do I need Hypoid Oil?

Thanks in advance
Chris

gallo, a good quality gear lube: 85W90 or equivalent will work just fine in both the transmission and the differential. If you have posi-traction (limited slip) in the rear you will need to add a bottle of additive for positraction differentials. I think it is a 6 or 8 ounce bottle. The additive should go in before the gear lube. Good luck!
