I'm with Muddy and Donald on the Redline products. It doesn't mean they are the best, it's just what I use. Other good products out there. Many say that Shell Rotella 15W40 is great for the primary as well as HD non synthetic primary oil. I would use a gear oil in the tranny and not a synthetic motor oil.

I change all 3 holes every 5,000 miles with Redline products. The tranny doesn't need to be done but it is easy to do and cheap insurance. I highly recommend changing the primary oil every 5,000 miles as the stuff that drains out contains clutch wear particles and needs to get out of there IMO..

Redline primary fluid in the primary and Amsoil Severe Gear 75W-90 in the tranny. I have tried the Redline Shockproof in the tranny, but I have found the Amsoil makes it a little quieter and easier to find neutral. Either way, can't go wrong.

And that's what you want...something heavier that hangs on the gears. Your bike will shift (and find neutral) much better.

I used Redline in the primary for quite some time. I then changed to 15w40 Shell Rotella (non synthetic) after seeing how well this oil held up in a industrial wet clutch system I had to try it. I am very happy with the results. Since changing over I have seen none to very little fuzz on the drain plug. With the Redline I was seeing a steady stack of fuzz every change. I also have better clutch disengagement so when I drop it in to gear I don't get that clunk just a nice click. Not saying don't use Redline they do make great products. Just letting people know my experience with Rotella in the primary.

In my EVO with the DD6 Baker I use Redline heavy shock proof in the tranny which was recommended by Baker at the time, it seems to work very well.
Baker now recommends the Spectro Tranny oil for the DD7, I haven't tried it yet but will whenever I get a chance to put in the DD7.
I have an S&S clutch in the EVO and S&S recommended ATF so I have been using Royal Purple ATF for years in the primary with this clutch it works very well and I have not even adjusted the primary chain this is behind a 127" motor with 145 hp. Baker recommends the Spectro Primary oil with their new Compensator which I ordered when I bought the compensator I will let you know how it works, once I get back from Overseas, (Maybe in Sept)

THE NEWER HARLEY 6 SPEED TRANSMISSION HAS A SMALL ORRIFCE GOING TO ONE OF THE ROLLER OR TAPERED BEARINGS. TO HEAVY OF OIL SUCH AS BELRAY AND HEAVY GEAR OIL WILL UNDER SERVICE THE BEARING AND CAUSE FAILURE. IF THIS HAPPENS UNDER WARRTY HARLEY WILL TAKE A OIL SAMPLE, HAVE THE OIL SENT TO A LAB, AND IF IT IS DETERMINED THAT HEAVY OIL WAS USED, THEY WILL NOT COVER THE REPAIR. THIS IS FROM A STEELER IN MICHIGAN

Define "Heavy". Harley uses a 75w90 gear oil in the standard bikes which has a viscosity that is roughly the same as a 50 weight motor oil like the SYN3 they use in a CVO. Redline Heavy Shockproof is a 75w90 rated gear oil, as is the Spectro product that was also mentioned. The fact that Redline uses the word "heavy" in the name of the product doesn't mean what most people seem to think it means. It just distinguishes between this normal weight gear oil and the "light" version they sell for racing differentials in cars (lower viscosity, less power loss).

Dealerships have been known to spread all sorts of BS to their customers. Don't automatically believe everything they tell you.

+1 on the AMSoil 75w90 for the tranny
I also use AMSoil primary fluid and their 20w50 in the engine.

Hummm. You got me thinking on this one.

I use Redline in trans and primary, Mobil 1 in engine. And contrary to what most say on here, I have a buddy who used SYN 3 in all holes and has for years, he had over 70k on last one when he traded and it was fine, I change it for him most times and what was drained looked OK every time. Never did an analysis but most of us ride less than a 100K before trading and apparently all current manufacturers products are quite up to the task of doing what needs to be done regardless of brand.
So use what makes you happy and ride on.

HarleyJeffOregon · « **Reply #17 on:** August 14, 2015, 05:08:58 PM »

I have been using syn3 in all holes for 85,000 miles. Still running strong.

grc · « **Reply #18 on:** August 14, 2015, 07:26:55 PM »

I've tried for years to convince people that SYN3 is a good product, but for whatever reason many seem to think otherwise. If a guy like me, with my oft stated feelings about the MoCo, admits that the stuff is good and probably better than more than half of the other choices on the market, I have to believe those who constantly bash it have never looked at any real data. If folks don't want to buy it because it's pushed by H-D, or because it's made by Citgo, fine by me. But if they don't buy it just because someone told them it's crap, they need to listen to someone who actually knows something about motor oils instead.

Btw, the attachment is from the comparison testing AMSOIL published in 2009. Note that SYN3 ranked fourth out of seventeen oils tested. Not that shabby.

SneakyPete · « **Reply #19 on:** August 14, 2015, 08:38:35 PM »

This is a timely thread as I've just finished changing both in my 2009 SERG.

For me the transmission fluid is easy. I've used Redline shockproof, Mobil 1 75w90, Belray 85w140 and now the new Amsoil Vtwin transmission oil. They all work well so it is just a matter of personal choice and what you have easy access to.

The primary oil is more tricky and I say that because it depends on the clutch you are using. Your choices are also complicated by the fact that your clutch requires a coolant and your compensator requires a lubricant. Not a big deal if you are running a stock clutch as HD formula + seems to work well, however, if you are running an after market Bandit, Rivera or Barnett the manufactures recommend ATF and ATF will not provide the lubrication needed by the compensator. So what do you do?

I'm running a Barnett Scorpion with lockup, SE compensator with GMR compensaver. I was experiencing some clutch chatter starting out in first gear, otherwise clutch worked great. Primary oil was Belray. Decided to change to Amsoil primary oil. Was better, but still chirped every once a awhile. Spoke to Steve at GMR and he recommended 26 oz Dex-Merc ATF mixed with 6 oz of the Amsoil primary oil (could be any suitable wet clutch oil) for compensator. I upped that to 32 oz ATF and 6 oz to get to the 38 oz needed. Results? No more chirp in first.

Clutches can also be sensitive to the amount of fluid as well. For a bone stock primary, the volume stated in the manual is fine, however, for the after market clutches I would say those volumes are guidelines. IMHO, you have to play with it a little for the results you desire.
