Engineered for Modern Fuel-Efficient Transmissions
AMSOIL Signature Series Fuel-Efficient Synthetic Automatic Transmission Fluid is formulated for modern transmissions that require lower-viscosity, fuel-efficient ATF. It provides outstanding protection against thermal breakdown, wear and sludge while helping maximize fuel efficiency and shift quality.
It is backward compatible and replaces DEXRON III fluids in older GM automatic transmissions. (DEXRON VI specification supersedes the obsolete DEXRON III in GM vehicles.) Also suitable for Toyota CVT applications calling for the Toyota "WS" specification.
Key Benefits
- Formulated for modern transmissions requiring fuel-efficient, low-viscosity ATF
- Pour point of -65°C (-85°F) — best cold-flow in the Signature Series ATF lineup
- Backward compatible — replaces DEXRON III in older GM transmissions
- Suitable for Toyota CVT applications calling for WS specification
- Outstanding friction durability for smooth, reliable shifts
- Protects against thermal breakdown, sludge and varnish
- Covers DEXRON VI, MERCON LV/SP, Toyota WS, Honda DW-1 and more
- Double the severe-service drain interval in passenger cars and light trucks
Cold-Flow Excellence and Wear Protection
Signature Series Fuel-Efficient ATF delivers an exceptional pour point of -65°C (-85°F) — the lowest in the Signature Series ATF lineup — for outstanding cold-weather shift response and warm-up performance.
Its synthetic formulation provides high film strength and premium anti-wear/extreme-pressure additives to protect gears and bearings under severe stress. Friction modifier additives deliver outstanding clutch-holding capacity, torque-transfer ability and anti-shudder properties for smooth, reliable shifts.
