MAG 1® Automatic Transmission Fluid

Passenger Car Transmission Products Automatic Transmission Products

MAG 1 Automatic Transmission Fluid is engineered to extend transmission life and smooth operation of Ford and General Motors vehicles where a DEXRON III/MERCON® fluid is specified. 

Protection for Today’s Automatic Transmission Designs

Automotive 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. 


  • Delivers superior friction stability to maintain smooth, consistent shifting and prevent shudder.


  • Provides a strong oil film to prevent metal-to-metal contact between rotating parts to prevent wear.    


  • Resists thickening due to high operating temperatures.    


  • Also recommended for all transmissions requiring DEXRON® II or IIE, or Type A transmission fluids.  Do not use this product in General Motors vehicles after model year 2005 and Ford® vehicles after model year 2006. Do not use this product in transmissions that specify Ford Type F, MERCON® V fluids or GM Dexron® VI fluid.
