yep. Some put Redline Shockproof in the Tranny, and use Type F Auto Trans fluid in the Primary. As long as whatever you put in the primary does not have friction modifier in it you will be fine. but you can use Vtwin in all 3 holes...

That stuff is pretty good. Just out of curiosity, did you say in another post that you were running in the motor? If so, I don't think synthetic oils are good to use when running your motor in. Stick to the good old mineral oil from Harley, Pennzoil, Penrite, etc.

Mineral Oil for break in period,
Synthetic after....
Thunder, Mobil1 V Twin can go in all holes,
and all the other brands now seem to have
Synthetics as well...
