AMSOIL makes synthetic transmission fluid for every drivetrain, including automatic transmission fluid (ATF), CVT and dual-clutch (DCT) fluid, manual synchromesh fluid and gear lube, powersports and V-twin fluid, and hydrostatic transmission fluid. This page lists all of them, plus engine and transmission flush for service prep.
Match the formula to the transmission type with the AMSOIL vehicle lookup guide, then open a product page for specs, package sizes, and the order link. Every order ships from AMSOIL, and adding an AMSOIL Preferred Customer membership to the same cart switches qualifying products to member pricing, up to 25% off.

Signature Series ULV ATF
Ultra-low-viscosity synthetic ATF for late-model automatics designed around thinner fluid. Keeps film strength and shift control where a heavier transmission fluid would be the wrong match.
View product
OE Multi-Vehicle ATF
Synthetic multi-vehicle automatic transmission fluid for drivers who stay on the factory drain schedule. Broad coverage for everyday car and light-truck automatics that call for a multi-vehicle ATF.
View product
OE Fuel-Efficient ATF
Lower-viscosity synthetic ATF in the OE line for transmissions that specify a fuel-efficient fluid. Supports clean, responsive shifts for cars and light trucks on a factory service schedule.
View product
Synthetic CVT Fluid
Dedicated synthetic CVT fluid for belt-drive and chain-drive continuously variable transmissions. The friction balance keeps power transfer smooth and helps prevent the shudder a wrong fluid can cause.
View product
Synthetic DCT Fluid
Synthetic dual-clutch transmission fluid built for precise wet-clutch control and fast, clean shifts. Protects gears and clutch packs through the heat of daily driving and hard performance use.
View product
Torque-Drive ATF
Heavy-duty synthetic automatic transmission fluid for severe service, commercial equipment, and long hours under load. Holds hydraulic control and clutch performance as sump temperatures climb.
View product
Super Shift Racing Transmission Fluid
Racing transmission fluid built for firm clutch engagement and stable viscosity under competition heat. Made for track and high-performance duty rather than routine street service.

Manual Synchromesh 5W-30
5W-30 synchromesh fluid for manual transmissions and transaxles that call for a synchromesh grade. Protects brass synchronizers and keeps shifts crisp from cold start through hot traffic.
View product
Manual Transmission Gear Lube 75W-90
75W-90 synthetic gear lube for manual transmissions and transaxles that specify this grade. Keeps its film strength through highway miles, loaded hauling, and hot, hard-working gear sets.
View product
Powershift SAE 10W
SAE 10W synthetic powershift transmission fluid for heavy equipment gearboxes, wet brakes, and hydraulic systems. Resists heat and oxidation through long operating hours in the field.
View product
Powershift SAE 30
SAE 30 synthetic powershift transmission fluid for equipment that specifies the middle grade. Holds viscosity and friction control under high load and rising sump temperatures.
View product
Powershift SAE 50
SAE 50 synthetic powershift transmission fluid for the heaviest equipment duty. Keeps its film strength when load, ambient heat, and continuous operation push lighter grades past their range.
View product
SAE 50 Long-Life Transmission Oil
Long-life SAE 50 synthetic transmission oil for gearboxes that call for this specific product. Resists heat and oxidation so protection lasts through extended service where the application allows.
View product
Dirt Bike Transmission Fluid
Synthetic dirt bike transmission fluid for separate gearboxes and wet clutches. Handles shock loads, mud, and hard shifting where passenger-car ATF chemistry does not belong.
View product
V-Twin Transmission Fluid
Synthetic V-twin transmission fluid for motorcycles that run a dedicated gearbox sump. Cushions gear teeth and keeps shift quality steady through highway miles and loaded touring.
View product
ATV/UTV Transmission & Differential Fluid
Synthetic ATV and UTV fluid for transmissions and differentials that share this fluid type. Protects gears and bearings through mud, water splash, and heavy trail loads.
View product
ATV/UTV Powertrain Fluid
Synthetic powertrain fluid for ATVs and UTVs that run one fluid across the powertrain. Balances clutch, gear, and bearing protection in a single fill for the combined duty.
View product
ATV/UTV Dual-Clutch Transmission Fluid
Powersports dual-clutch fluid for ATV and UTV gearboxes that need precise wet-clutch control. Built for trail heat and repeated shifts that a general-purpose gear lube cannot cover.
View product
ATV/UTV CVT Fluid
Synthetic CVT fluid for ATV and UTV belt-drive systems. The friction balance keeps belt power transfer clean while the synthetic base handles heat from mud, dunes, and loaded trail work.
View product
Hydrostatic Transmission Fluid 20W-50
20W-50 synthetic hydrostatic transmission fluid for zero-turn mowers, garden tractors, and similar equipment. Keeps film strength when continuous pump and motor loads raise fluid temperature.
View product
Engine and Transmission Flush
Service-prep flush that helps loosen sludge and deposits before an engine oil or transmission fluid change. Used ahead of the fresh fill, not as a replacement for the finished lubricant.
