Customer Ratings & Reviews

Bought this along with the primary fluid for my 2012 harley Davidson 103 six speed and so far I'm happy with the product seems to be less noise and easier shifting and easier to find neutral we will see long term

I have 49K miles on my 2007 Harley Davidson Fatboy motorcycle. In all those miles and years, I have always used AMSOIL Synthetic Transmission Fluid. At every fluid change interval there has been no wear metal dust on the drain plug magnet. The transmission is very quiet, & shifts very well while in operation. No noise in 5th or 6th gears. I highly recommend AMSOIL Synthetic Transmission Fluid.

Smooth

I have been using it since it came out. Works very good.

Highly recommended for my Harley

Great oil. Highly recommended!

Have always put this in my trans. Runs quiet and I've never had a problem with my trans! Talked a few of my brothers into going with it.

Shifts like butter, finds neutral like it never has before. It’s the best

Great product

Great product better than just running oil.

Wanted to try this for the transmission I have always used the engine oil but first time for transmission. And I have no complaints. Great product.

First time trying the transmission fluid for my Harley with a M8. Shifting seems to be smoother with this oil.

It's fine.

1st time using it shifts a lot smoother

Stops the clunk!

600 miles on this first time use. Quiteter and smoother shifts

Feels better than previous changes. Great product.

Was time for an oil change, and have been using AmsOil products in my truck since 2016. I've tried other oil products in my truck and have not liked the outcome. Harley-Davidson does make a good product for their bikes, AmsOil just does a better job especially during warmer climates or heavy traffic when oil breaks down faster. I have never tried AmsOil XMSN Fluid, with summer on the way I will give it a try.

I run this in my M8 117 Softail. It’s works terrific! Fluid is always new looking when I change every 3k miles.

When I started using this Transmission Fluid in my bike, the shifts are quieter and seem smoother to me. Nuetral is easier to shift into, which can be a chore on these motorcycles at times. That problem has become a non issue since using the AMSoil. I use AMSoil in "all three holes" on my own bike, with confidence. The finest lubrication available for a V-twin power train. Extremely happy with AMSoil products, will use no others in my ride.
