A couple of simple gears in an iron housing. 2400 RPM 1800 RPM out. Manufacturer is not much help. They specify 80W 90 with .05 gal "enhancer". I don't think we are going to get much more from their support clowns. Enhancer makes me think limited slip modifier, but why would that be needed in a simple gear box? Should we use 80W90 clear transmission oil or stinky rear axle stuff?
