Dedicated Transmission Fluid for Smooth, Quiet Shifts
AMSOIL Synthetic V-Twin 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 you focus on enjoying the ride.
AMSOIL Synthetic V-Twin 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.
Key Benefits
- Purpose-built for V-twin transmissions — not a multi-use compromise
- Delivers smooth shifts for crisp acceleration through each gear
- Dampens loud thunks and reduces gear noise
- Resists viscosity loss due to shear under extreme pressures
- Extreme-pressure additives protect gears and bearings against wear
- Superior film strength protects against shock-loading damage
- 20,000-mile service life for extended protection
- Warranty Secure — keeps factory warranty intact
Protects Gears and Bearings, Eliminates Noise
AMSOIL Synthetic V-Twin Transmission Fluid forms a durable oil film on bearings and gears, helping to dampen loud thunks when shifting and reduce gear noise.
Extreme pressures between gear teeth can shear inferior transmission fluids, reducing viscosity and compromising wear protection. AMSOIL Synthetic V-Twin 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 its extreme-pressure additives deliver additional protection against wear.
Its finely tuned viscometrics and frictional properties provide smooth shifts, helping you avoid missed shifts for crisp acceleration through each gear.

Great product and the transmission shifts smoothly
Tranny fluid
Tranny seems so much happier for sure
Probably a good product but too thin.
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.
Good fluid
Did not include O-Ring for the drain plug
Not impressed
I was originally using the severe duty 75-140 transmission lube. After switching to the synthetic V-twin , I have harsher shifts and a harder time finding neutral.
