The dealer puts the same oil in all three holes, and that's good enough to satisfy factory warranty etc, but as long as you're upgrading to Amsoil you should put the appropriate fluid for each application. Specifically, gear oil in the trans is better than engine oil. Again, oil is "good enough" and won't hurt anything, but feel free to upgrade because you certainly don't have to use the same fluid for engine/trans/primary.

 

i agree with not putting the same in all three. how could something designed for the pressures of pumping and the combustion temperatures be good for your clutch or hold up in the transmission. im getting BG synthetic trans and engine oil. using normal primary fluid.
