You can go to Amsoil's website and see their recommendations. IIRC, they recommend the 20-50 for all three, but also provide alternative recommendations.

Correct, their recommendation is 20W-50 in all three. The 110 or 140 gear lube can be used in the tranny. There are some who like the 10W-40 in the primary. Several combinations possible, all will work.

75 90 is ok for colder climates but the 110 or 140 will quiet down the 5 gear whine a little more .
