What color is the fluid?

The primary case fluid is amber colored. You may be thinking about the Heavy Shockproof Transmission fluid which is pink.

Can this be used in a can am outlander atv?

this is for a wet clutch where the transmission and primary do not share the same fluid

Any compatibility issues removing amsoil from primary and replacing with red line?

Don't know I was running HD primary oil but I don't think there would be any issues it doesn't circulate through the engine or tranny.
