O7 Six Speed Gear Lube

O7 Six Speed Gear Lube
I've got a 2007 Street Glide with about 3,000 miles. I installed the SE synthetic gear lube at 1,000 miles but can't say I really noticed any difference, the transmission is still too noisy,particularly in 5th gear. I've read several articles about different gear lubes, but have never seen any recommendations from someone who actually used a specific product with positive results. I've been looking at Amsoil, Redline, Bel-ray, etc. Anyone experienced any noticeable improvement with one of these or other similar products?

RE: O7 Six Speed Gear Lube
mine got quieter with amsoil severe gear. probably 20% reduction. miles will help it to quiet down even more. Also if you get rid of the stock mufflers and put sumfin a lil louder... you won't notice it at all.
My 5th gear really quieted down around 5k. If I 'try and hear it'... I can at 8k but it is barely audible (maybe my hearing is going .... I dunno).

RE: O7 Six Speed Gear Lube
Iswitched from Syn3 toRed Line Heavy Duty Shockproof in the tranny of my 07FLHTCat 2Kmi.Noticeably quieter, especially in 5th gear.AfterI hit 5K miit is even quieter,but I think it has more to do with wearing in, etc and not as much todo withloss of hearing.
At theupcoming 5K service interval I'm going all the way with Red Line: 20W50 (SM/SL/SG/CF)in the case andMTL in the primary. Iexpect the engine temp will drop a bit, which will be well received by me and my wife.
I used Red Line in all cavities in my hopped-up 96 Dyna and was extremely pleased with the overall performance.
On a related note, when I tried to get a handle on the service classes (certification)ofHarley engineoil products I couldn't find any reference to it until I ran across a small recommendation in the Touring Models 2007 H-D Owner's Manual, page 139. It says in part that if you're unable to secure H-D oil then use an oil certified for diesel engines CF-4, CG-4, CI-4 until you can see an authorized H-D dealer to change back to 100% H-D oil. Red Line Diesel oil 15W40 iscompliant withthat recommendation.
Another way for the Motor Company to possibly deny warranty claims. Wherein lies the truth?
