Synthetic V-Twin Transmission FluidAMSOIL V-Twin Synthetic Transmission Fluid is specifically designed for bikers who prefer a dedicated transmission fluid over a multi-use lubricant. Its frictional properties deliver smooth shifts and it helps quiet transmission noise, letting riders focus on enjoying the ride. V-Twin Synthetic Transmission Fluid is Warranty Secure™ and will not void your motorcycle’s warranty. It is a cost-effective, high-performance alternative to original equipment manufacturer (OEM) fluids.

Promotes Quiet Operation

V-Twin Synthetic Transmission Fluid promotes formation of a durable oil film on bearings and gears, helping to dampen loud thunks when shifting and reduce gear noise.

Protects Against Gear and Bearing Wear

Extreme pressures between gear teeth can shear inferior transmission fluids, reducing viscosity and compromising wear protection. AMSOIL V-Twin Synthetic Transmission Fluid resists viscosity loss due to shear and withstands extreme heat for excellent wear protection. Its robust molecules provide film strength to protect against damage from shock loading, while it contains extreme-pressure additives for additional protection against wear.

Customer Testimonials:

No more “thunk”

Switched to a dedicated synthetic Transmission lube, due to the OEM Synthetic taking out the double roller bearing on a long trip so I learned my lesson and no longer use one in all three. Noticeably less noise, easier shifting and longer life than OEM, and the RED stuff they put in when the transmission was rebuilt in Canada didn’t even last a day before shifting was hard and noisy.

Synthetic V-Twin Trans Oil

Best stuff ever!! Used in Harley Street Glide Trans and get rid of all noise that harley oil has.. Would recommend to anyone!!

Smooth Gear Shifts

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.
