shifts well even in cold weather.maybe a little thicker.cause we don,t know the viscosity
Reviewed by James:
I use this in my 13 Harley Davidson 6 speed. Noticeable difference when shifting. Smoother, quieter eliminates much of the shifting to 1st gear clunk along with finding neutral easier.
Also designed specifically for transmission. Another wise choice if you want your ride to last.

Even though Harley says you can use the same oil in all 3 engine sections, why do that when you can have a fluid specifically tailored to your tranny.

Reviewed by Tim:
This is the first time I've used anything other than Amzoil 20/50 motorcycle engine oil in the transmission of my 2013 Harley Davidson Streetglide. I noticed right away that it shifts smoother. Especially after the engine and transmission are running at their full operating temperature. When I'm at a stop light and idling in neutral, If I pull in the the clutch and if I hold it for a couple seconds before shifting into first gear and it just slides right in as smooth as ever and doesn't even make a noise. Overall it just shifts smoother, I'm glad I took a chance and switched to this.

I have been using Amsoil for a long time on many different motorcycles. Amsoil has a keep it simple process, if you need oil for engine, transmission or primary just order for that specific place.
Always the same quality performance oils and I've never had a
problem.
Thanks much!

This is the best transmission fluid around for your Harley. I don't like the idea of using the same fluid for tranny and primary seeing my bike is 27 years old. I found she shifted smoother and quieter then before.

I use Synthetic V-Twin Transmission Fluid in the transmission on my Harley-Davidson Heritage.
I believe you need to use a lubricant that is made for the specific job it does. I don't believe you should use engine oil in transmission or primary chain case. Each application has different requirements for lubrication.
It would be nice if a color was added to the transmission fluid. It is difficult to see the clear fluid level on the transmission dip stick.

I know most of the big bikes these days are engineered to be hammered on without worrying about breaking down too fast for wear and tear. I prefer to baby my equipment as best I can though. I appreciate the crazy money these things are worth and so far Amsoil is the best reassurance I have for my investment and preventing it all from wearing way too fast. The little magnetic bolt in the Harley transmission case comes away clean when I use this stuff, so that tells me it's doing the job right. I'll keep using as long as that's the case.

Bought a 2011 cop bike with 70000 miles on it with all the stock Harley fluids in it. Did a 10000 mile service, all 3 holes. When I rode the bike with the new tranny oil it was a new bike, got neutral easily, smoother shifts, it feels like it coupled with the primary fluid makes it easier to navigate the cone course, much smoother.

I was using competitor's 85/140 Hypoid in my Harley's transmission and switched to Amsoil transmission fluid. It was immediately apparent that it's too thin. The gears were clunkier and loud. After 1000 miles I switched to Amsoil Severe Gear 75/140. Problem solved, back to quiet and smooth again. Will stay with Amsoil Severe Gear.

I can't believe how much easier the bike shifts from gear to gear since I changed to this transmission fluid. It is a real noticeable difference.
Reviewed by Charlie P:
Changed the fluids on two holes (Crank & Tranny) on my 2016 Harley Softail Deluxe. Used Amsoil fluids for both. This was the first fluid change I personally did since the factory warranty at 1,000 miles. Factory had used some other synthetic fluid which was an improvement from non-synthetic. But what an incredible difference after doing my own and switching to Amsoil. My moto seriously runs much cooler and the tranny feels great when shifting. I fell in love my bike all over again. Plan on continuing to use and will soon try out the Amsoil primary fluid.
Reviewed by Frank:
This really made a difference with the loud clunking when I shift gears.
I first used Red Line and it sounded quieter the first couple times riding after oil change but got back to loud
clunking, I tried Amsoil and after 2000 miles I am very satisfied and will use this from now on.
