Transmission... any good 75w140 or 75w150 like the mobil one synthetic will be fine.
Primary...regular 20w50 motor oil, dextron 3 or 5 mercon, trick shift,or hot shift.

thank you Bobby. i ended up having a buddy of mine pick up a quart of the 20w 50 synthetic oil at the Harley and bring it to me. the dealership said i can use the 20w 50 oil for primary, transmission and engine.... does it sound right to you?

You can in the motor or primary but that is way too thin for the protection of the transmission.

My suggestion and what I like to use,
Syn 20w50 in the engine.Like mobil 1 etc.

Reg 20w50,primary... Change it often so it gets the friction dust out and I dont like to use synthetic here as it can cause clutch slippage.

Syn75w140 or 75w150 in the trans... Change it often so the bearings can live.
