The detergants in motor oil are not capable of holding metal shavings in suspension like it can combustables so this theory is all wrong. Also once break in has occurred you should not keep making shavings or something is wrong with the tranny. Use whatever product you feel comfortable with.

Yep, agreed.

Transmission I use a 85-140 fully synth Gear oil. Smooth as silk gear changes and protects the gears very well.

Other holes I use a 20W-60 fully synth.

Primary oil is only there to lube the chain drive, cool the clutch and wash any wear particles to the bottom of the case to get them out of the way until the next change

Been using this combo for years trouble free.

Not sure what brands you have available local over in the US but I use Penrite in Australia

Not a correct assumption on the primary.

Our bikes, unless modified to a belt primary drive, use wet clutches. Similar to the automatic transmission in most cars, they are designed to slip and need proper lubrication.

I'm quite certain piss, even highly exotic, synthetic goat piss, wouldn't adequately protect the components in your primary case.

Turk05 wants to know Dino or Syn?
My service guy at the dealer mentioned that while they are fine with good quality synthetic oil in the engine, and they put Redline in their transmissions, (except Bakers that call for ATF I believe) but he was adamant that the primary should have the Harley fluid in there. He said they had seen enough primary issues with many other fluids, so they stick with the HD and have good results. Just something to consider...

I tried the redline 80 - 140 ( the green stuff) and I didn't like it at all. shifts were harder ( 06 Fatboy) and it just clunked more. that was at 10K miles after using harley gear oil.. I just switched the Syn 3 and it seems to be the best its been for shifting smoothness.

Is the Shockproof the 240 wt ( pink stuff) Thanks

I just recently switched from Spectro's synthetic heavy duty tranny oil to Royal Purple heavy duty tranny oil as well as Spectro's primary oil to a Dex ATF fluid.

All I can say is WOW!!!

What a difference!

I mean, WOW, I can't tell any difference. Bike still shifts and changes gears just fine.

The main reason I switched was to have different color fluids as I have a random seepage issue I want to track down.

Any primary fluid like Rev Tec, Drag Specialties, HD Formula +, Bel-Ray(it's red like atf) that you can get the easiest is fine. Any trans fluid meeting the specs for these transmissions is fine. None of them will facilitate easier or quieter shifting despite what you read.

I agree 100% -- the person who thinks it doesn't make a difference has obviously not tried Redline Heavy Shockproof.

I have it in my bike now, ZERO difference between that and HD Formula+ . It isn't going back in at the price they want for it.

Shockproof goes in the transmission, not the primary.

If you would actually look into fluid recommendations rather than just pour in whatever some counter jockey sold you would find out that HD Formula+ is recommended for the transmission and primary and is factory fill in most if not all big twin primaries and transmissions.

I use all amsoil. 20w50 in engine. Severe gear in tranny and super shift in primary. No issues or complaints.

Using the same oil in all 3 holes just doesn't make sense to me. Would u put heavy gear oil in your engine? Your tranny is a bunch of gears so use gear oil. Your primary is a wet clutch so use something designed for that purpose not an all-in one type thing. Just my 2cents..

Actually no, I haven't tried it. Being that it is 75W250 as apposed to the others I tried which are ~75W90/75W140, perhaps there may be a slightly noticeable difference.

If one was going from 20w50 to 75W250, sure I would bet there may be a noticeable difference. Putting engine oil in the tranny (or primary) makes no sense to me either.

I guess the more specific point I should of emphasized was that changing oil brands\types with the similar viscosity in the primary\tranny; there shouldn't be any noticeable difference in noise\shifting etc...

Will I try redline shockproof? Maybe, maybe not, tranny works and shifts fine.
