Modern automatic transmissions are more complicated than their predecessors. Today's designs feature more gears, clutch packs and narrow oil passageways that require a steady supply of high-quality fluid. Without it, wear and sludge formation can lead to reduced performance and even failure, requiring thousands of dollars in repairs. AMSOIL OE Synthetic Automatic Transmission Fluid provides passenger-car/light-truck transmissions excellent wear protection, sludge resistance and extreme-temperature performance throughout original equipment manufacturer (OEM)-recommended drain intervals.

Outstanding Wear Protection

AMSOIL OE Synthetic ATF is durable. In normal and severe service, it resists wear to the transmission's valve body, gears, clutch plates and other vital parts, helping today's complex and demanding transmissions achieve long life.

Resists Varnish

In elevated heat, AMSOIL OE Synthetic ATF's thermally stable formulation guards against the harmful effects of thermal breakdown. It resists the formation of varnish that can stick valves, threatening transmission performance and life. OE Synthetic ATF also resists heat-related evaporation and viscosity loss to help components stay clean and remain protected.

Reliable Cold-Weather Performance

AMSOIL OE Synthetic ATF remains fluid in sub-zero temperatures. It resists thickening and flows quickly for fast, reliable shifts during cold starts. Its excellent low-temperature fluidity also maximizes fuel efficiency.

Excellent Leak Protection

Formulated with seal conditioners, AMSOIL OE Synthetic ATF helps prevent seals and gaskets from drying out and cracking, reducing the risk of fluid leaks.

Promotes Smooth, Shudder-Free Shifts

AMSOIL OE Synthetic ATF is formulated with friction modifiers that promote fast, smooth clutch engagement. As a result, drivers experience fast shift response and torque transfer for maximum drivability.
