Heavy Duty Truck Transmission Fluid

Automatic Transmission Products

Evolutionary Performance™

Heavy duty truck transmissions have evolved dramatically, requiring highly specialized fluids for unique applications. One brand has evolved right alongside – MAG 1®. Only the most advanced transmission fluids meet the difficult challenges of effectively balancing performance, strength and durability.

Featuring MAG 1® with FMX® Technology - Friction Management for Xtreme protection™ FMX technology provides unsurpassed protection and performance.

Performance

Delivers superior friction stability to maintain smooth, consistent shifting and reduce shudder

Strength

Provides a strong fluid film to prevent metal-to-metal contact between rotating parts to prevent wear

Durability

Resists thickening due to high operating temperatures

Powerful Chemistry and Performance

MAG 1 helps optimize the friction, torque and function of your equipment to optimize performance and longevity.
