SUPER ATF

The High-Quality Performance Standard for Legacy Domestic and Import Transmissions

Close

Phillips 66® Super ATF is a high-quality automatic transmission fluid recommended for use in all domestic and import vehicles no longer under warranty where the OEM previously specified a GM DEXRON®-III H or Ford MERCON® fluid. This versatile lubricant is formulated to provide reliable performance in older planetary gearsets, offering a cost-effective alternative to synthetic-blend fluids while maintaining the strict frictional requirements of legacy transmissions. Its robust formulation resists oxidation and thermal breakdown, ensuring that high-hour gearboxes continue to shift smoothly and remain free of performance-robbing sludge and varnish.

PRODUCT RESOURCES 

PERFORMANCE

  • Smooth Engagement: Balanced frictional properties provide consistent shift feel and prevent torque converter shudder in older units.

  • Thermal Endurance: High-quality mineral base stocks resist thinning and chemical breakdown during high-heat operation.

  • Low-Temp Fluidity: Engineered for excellent pumpability at low temperatures to ensure immediate hydraulic response at startup.

PROTECTION

  • Wear Defense: Fortified with specialized anti-wear additives to protect internal bushings, thrust washers, and planetary gears.

  • Corrosion Shield: Provides a chemical barrier against rust and corrosion of critical copper-clad and steel components.

  • Seal Compatibility: Specifically formulated to keep older elastomeric seals pliable, helping to prevent hardening and external leaks.

UPTIME

  • Varnish Control: Prevents the accumulation of sludge and deposits that can cause solenoid sticking and valve body malfunctions.

  • Versatile Application: Serves as a multi-use fluid for both automotive transmissions and industrial hydraulic systems.

  • Foam Resistance: Maintains a stable hydraulic stream to prevent air entrainment and spongy shifting in high-mileage gearboxes.

FEATURES & BENEFITS

  • Legacy Optimized: Perfect for 2005 and earlier GM and Ford vehicles requiring Dexron-III or Mercon ATF.

  • Anti-Shudder Tech: Maintains the friction coefficient required to stop torque converter vibration in high-hour vehicles.

  • Oxidation Stability: Significantly outlasts economy-tier fluids, extending the life of the transmission internal components.

  • Hydrostatic Capability: Suitable for use in mobile and industrial hydraulic systems operating over wide temperature ranges.

  • Seal Guard: Contains conditioning agents that help maintain internal pressure by keeping gaskets in peak condition.

APPLICATIONS

  • GM and Ford automatic transmissions (2005 and earlier) no longer requiring warranty-compliant fluids.

  • Import vehicles where an obsolete DEXRON®-III H or earlier-generation fluid is specified.

  • Allison heavy-duty off-highway automatic transmissions requiring a C-4 quality fluid.

  • Industrial and mobile hydraulic systems requiring an anti-wear ISO 32 or 46 weight fluid.

Licenses & Approvals:
  • Meets performance requirements for DEXRON®-III H (Obsolete)

  • Meets performance requirements for MERCON® (Obsolete)

  • Recommended for use where Allison C-4 is specified.

MAMMOTH TECHNICAL TIP:

In the world of high-hour transmissions like the GM 4L80E or Ford E4OD, "upgrading" to a modern Low-Viscosity (LV) fluid can actually lead to internal pressure loss and soft shifting due to the larger mechanical clearances in older valve bodies. Super ATF maintains the specific kinematic viscosity—7.0 cSt—that these units were hydraulically mapped for. When performing a pan-drop service on an older rig, the high Viscosity Index (188) of Super ATF is your best defense against "morning sickness" (delayed engagement when cold). It ensures that the pump can prime the circuit instantly, preventing the momentary clutch-drag that causes friction material to flake off over time.
