Southern MN

I have a 1973 Chevy C-65 and found the service manuals online for the Spicer transmissions here: http://partsmanuals.org/spicer-service-manuals/

I bought 5 gallons of straight 50w engine oil off of Amazon for about $70 delivered to my door and use that.

A question I have is how hot should the transmission cases get while working? I can place my hand on the transmission case for about 5 seconds, then I need to pull it off. Is that too hot or normal?

Here is what the service manual specifies for oil:
