Amsoil Tranny only fluid
Synthetic in the primary? Whatever happened to regular old oil or ATF in the primary? I'd be curious to see how the AMSOIL performs at 4 or 5K.....

I'm running Amsoil 20/50 in my engine, their new transmission lube (I thinks it's 75/90 with a new label) in the transmission and their new "primary fluid" in the primary.
The engine is a little quieter, the transmission is a little quieter, shifts without such a loud clunk, and neutral is MUCH easier to find. Primary is quieter. Not so sure how necessary the primary "fluid" is. 20/50 will work in all three. Whatever I use I need 38oz for the primary so 1 qt ain't gonna do it.

I was thinking of switching to the red line heavy shock for my trans. I run amsoil 20w50 MC oil in my V rod an it shifts better an the clutch feel was a big improvement.
