Each transmission type runs on chemistry built specifically for it. These fluids are not interchangeable — using the wrong one can cause shudder, slip, or premature failure.

|---|---|---|---|---|
| Primary job | Hydraulic + lube + cooling | Belt/chain friction control | Gear lube + wet-clutch friction | Gear & synchro protection |
| Friction profile | Slip-then-lock clutch | High static, controlled slip | Crisp clutch engagement, no shudder | Synchro-compatible (no EP overload) |
| Typical viscosity | ULV / LV (≈4.5–7.5 cSt) | Low–medium (purpose-built) | Medium (≈6–8 cSt) | 75W-90 / 5W-30 synchromesh |

Your transmission is one of the most expensive components in your vehicle — and the fluid running through it is its lifeblood. AMSOIL synthetic transmission fluids are engineered for every modern transmission type, from ultra-low-viscosity 10-speed automatics to heavy-duty Allison fleet transmissions, dual-clutch gearboxes, CVTs, manual transaxles, V-Twin motorcycles, and zero-turn mower hydrostatic drives.
Modern automatic transmissions run hotter, shift faster, and demand more from their fluid than ever before. AMSOIL Signature Series Fuel-Efficient ATF, ULV ATF, and Multi-Vehicle ATF cover virtually every car and light truck on the road, while Torque-Drive and Super Shift handle Allison commercial and high-performance racing transmissions. For CVT and DCT applications, AMSOIL offers dedicated synthetic fluids that are not interchangeable with conventional ATF.
Manual transmissions need fluid matched to the gearbox design. GM, Chrysler, and many imports specify synchromesh-type fluid (use AMSOIL 5W-30 Manual Synchromesh). Other manuals and transaxles call for an API GL-4 75W-90 gear lube. Heavy-duty Class 8 trucks and off-highway equipment use AMSOIL Powershift fluids in SAE 10W, 30, and 50 grades, plus the long-life FTF SAE 50 for Eaton extended-drain applications.
Motorcycle and powersports gearboxes run wet clutches that demand specialized friction chemistry. AMSOIL V-Twin Transmission and Primary Fluids are formulated for Harley-Davidson and other V-Twin motorcycles. The ATV/UTV lineup covers transmission/differential, powertrain, dual-clutch, and CVT applications for Polaris, Can-Am, Honda, Yamaha, and Kawasaki side-by-sides. Two-stroke dirt bikes get a dedicated SAE 80 transmission fluid for crisp shifting and consistent clutch feel.
Zero-turn mowers, garden tractors, and other hydrostatic-drive equipment use a dedicated hydrostatic fluid that must maintain consistent viscosity at high temperatures and resist shear in the closed-loop pump system. AMSOIL 20W-50 100% Synthetic Hydrostatic Transmission Fluid is engineered specifically for this application — extending pump life and keeping drive performance consistent through hot summer mowing.
