ATF my man, ATF (automatic transmission fluid).
It's cheap, can be found anywhere, and designed exactly for this application (HD primary). I have countless years and miles using ATF in the primary - with zero negative issues.

 

I use the B&M non-syn quick shift, no issues.

 

Your not the only guy using tranny fluid. I would try it but tranny fluids have large amounts of friction modifiers. I don't know which ones don't.
So I am sticking with rotella. JASO ma rated.
And cheap.

 

FWIW, Type F ATF is was was recommended to me and I believe I even read that on one of the replacement clutch manufacturer's website (of course I can't find it now). It's designed for older automatic transmissions and designed to lubricate and keep parts cool while allowing good lockup of the clutch plates (and cheap). Just in case you ever want to give it a try.

To the OP - in my opinion, there isn't really a good "one bottle for all 3" oil. Each component (primary, engine, and trans) have different requirements and are best served with an oil designed for each specific application. But that's just me...

 

I tried using ATF (M1 synthetic) and it made my primary very loud and the shift clanky...not to mention it stunk up my garage after I drained it out to the point that my wife asked me if there was something dead in there. No there's nothing wrong with my stator, sniffing the jug confirmed it smelled putrid. Rotella is my weapon of choice.

 

Type f eh. Alright. Thanks

 

Not trying to be the "rightest" guy here but fear not the ATF.
Type 'F' has the additional friction modifiers you're so scared of. Type'F' was designed for early Ford automatics - thus the 'F'. Never heard of it hurting anything it was used in including HD primaries (AND GM automatics). Regular ATF (GM style) in an early Ford auto-tranny makes them slip right away.
Like I said, probably have accumulated 250K+ miles on several different HD's, all with ATF in the primary - no issues to date. The last stuff I bought was $1.45/qt. - still have a bunch left.
Never used (or smelled) syn ATF. The dino stuff works so well that I don't see any point in even trying a syn (especially if they're stinky like gear lube).

 

now how much do you use?the book says 38ozs.but a quart is 32ozs.does anyone buy the extra 6 ozs?

 

There have been numerous threads regarding SE compensators where they had fretting with the ATF. I would stay with motor oil or a purpose made primary oil, like H-D Formula +. I use Harley's SYN3 (probably the only one on here who does, or admits to it) with no problems at all.

 

+1 HD Formula Plus in the primary and Redline Heavy Shockproof in tranny !
