Now that the subject of lubrication has been brought up, here is my 2 cents: 600W was good 100 years ago. Modern gear lube deposits a coating on the metal parts that wears instead of the metal. The coating is constantly be re deposited. Use 85W-140 G5 in your transmission.
I wonder how many times 100 years ago someone said " good enough, it'll out last me"
