I've probably only got 75,000mi or so since I started using ATF, but I've yet to have anything in the primary(s) fail yet. As long as your aware of the type of fluid you're running, and it's advantages and limitations you'll be good. There's no unicorn blood in Harley fluids that makes them the only thug you can use...
Its not my discription. I went searching for backup to what you and i were saying..............I stole the post.

WOW Perki48.

You have nailed it with a write up like that. I have been a gear head for 30+ years and am not very good at writing like you did but you have stated the facts.
I am in total agreement. I use Dextron III synthetic in my primary with the same results you stated.

PS those who disagree or question his facts need to do a lot of research to acquire Perki48's knowledge.

Good find then, glad you posted it. After reading that I might run some dex iii on my 2009, since I don't beat on it as hard as the hot rod. I love having the B&M in the 1990 when it comes to track time or just bs'in and poppin wheelies or spinnin tires though lol

Found this when I googled Synthetic Dexron III

B&M
B&M Synthetic Trick Shift Trans Fluid

Product images may differ from actual product appearance.

Formulated for late model vehicles
B&M's synthetic Trick Shift is formulated as a performance automatic transmission fluid. Features the latest synthetic fluid technology, suitable for late model automatic transmissions. Not an additive, this safe and effective formula of extreme pressure agents, foam inhibitors and exceptional thermal stability will provide a long service life for your automatic transmission. Ideal for street use and high performance applications including racing, off-road, towing and heavy duty fleet use. Synthetic Trick Shift may be mixed with all other types of ATF but works best by itself. With B&M synthetic Trick Shift you can ''pour in performance''. Meets or exceeds Mercon or Dexron III requirements. 1-quart of cool blue color.

Default Now I am really confused...LOL

OK Lots of folks like to use ATF in the primary case. Lots of folks said DEX 3 but DEX3 has friction modifiers. I was told to use ATF type D or type F.
It was my understanding that DEX 3 with friction modifiers could damage the clutch plates, and cause problems !!! Have I missed something or just got bum info? Here is a link to using TYPE D or TYPE F ATF.

Dexron II and III are the most commonly used fluids with the only difference being additives in Dexron III to make it more compatible with the electronics used in modern transmissions.
They both have an additive package that includes friction modifiers for smoother cluch engagement, oxidation control, viscosity stabilizers, corrosion inhibitors and proper lubrication of bearings and bushings of all types. Since the advent of gerotor pumps and better friction materials such as Kevlar and Aramid, Dexron II or III has even replaced the use of Type F for racing use by most transmission builders.
Dexron III is commonly used in many automotive manual tranmissions and is probably used in more transfer cases of 4WD vehicles than any other fluid.
Sounds like the friction modifiers arent a problem for the clutch. I used to run only Type F, but at the recommendation of my clutch manufacturer I switched to B&M Trick Shift. Apparently B&M "meets or exceeds Dex III requirements", leading me to believe its synthetic and probably has similar friction modifiers. Ive been running B&M for about 30k miles with no problems. Ran Type F for about 50k prior, no issues there either

Default Thank you one and all for all the help, just one more question

I know the primary case takes one quart or until the fluid comes up to the radial spring. That said How much oil goes into the tranny and the motor, or what are the guide lines? I have no manual for my bike at this time and need to know before i do the 3 hole service. Thanks in advance. This is indeed a great site for info on these fine machines.
kindly
