Best Automotive Performance Transmission Cooler Fluids in 2026

Backward compatible with previous Dexron automatic transmission fluids and can be used as a much-improved replacement for older vehicles/transmissions originally using previous Dexron fluids

Improved performance over previous Dexron fluids in: friction durability, viscosity stability, aeration and foam control, and oxidation resistance

Potential to enable improved fuel economy and longer transmission life

SUITABLE FOR USE IN 95% of ATF VEHICLES in operation with US registered light duty applications.

HIGH PERFORMANCE CONDITIONING AGENTS prolong seal elasticity to prevent leaks

IMPROVE DURABILITY & TRANSMISSION LIFE with anti-wear technology to avoid costly repairs

EXCEEDS DEMANDS OF AUTOMATIC TRANSMISSIONS of most Chrysler, Dodge, Ram & other Stellantis vehicles

HIGH-EFFICIENCY CONDITIONERS protect and prolong the elasticity of seals, preventing leaks

ADVANCED TECHNOLOGY REDUCES WEAR, foaming, and oxidation while protecting transmission performance

High Film Strength Helps to Dramatically Reduce Heat and Wear

Automatic Transmissions Generate a Great Deal of Heat and Depend on Transmission Fluid for Cooling and Protection

Significantly Reduces Heat to Extend the Life of Your Transmission

Backward compatible with previous DEXRON automatic transmission fluids and can be used as a much-improved replacement for older vehicles/transmissions originally using previous DEXRON fluids

Improved performance over previous DEXRON fluids in: friction durability, viscosity stability, aeration and foam control, and oxidation resistance.

Designed for anti-wear protection and shear stability

BG ATC Plus enhances properties of both new and used automatic transmission fluid.

It improves fluid oxidation stability, thereby prolonging fluid life and the life of the transmission.

It prevents leaks by conditioning hardened seals-keeping them soft and pliable.

Fits all CVT transmissions from Japanese, German, and US vehicles. Outperforms most OEM fluids for both CHAIN and BELT CVT transmissions. TRIAX SYNTRON CVT SYNTHETIC is also recommended for and compatible with certain transmissions manufactured by Mercedes, Suzuki, Hyundai, Kia, and others.

10-15 degrees lower transmission operational temperature in most cases. Excellent hot/cold temperature performance. It helps to control transmission shudder and provides excellent vehicle driveability. It provides a wide range of seal compatibility, not harmful to synthetic rubber seals.
