Purpose and Specifications

Valvoline Heavy Duty ATF Pro is a premium full synthetic automatic transmission fluid designed for trucks, buses, and heavy-duty vehicles. It delivers superior protection against wear, corrosion, oxidation, foaming, and deposits, ensuring smooth shifting and long transmission life even under high-stress conditions.

This 1-liter bottle uses advanced synthetic base oils that maintain stable viscosity across a wide temperature range, from very low temps down to -40°C for easy cold starts to high operating temps up to 150°C without breaking down. Special low-friction additives prevent stick-slip for effortless gear changes, while excellent thermal stability resists aging for reliable performance over extended periods.

• Key Benefits: Enhanced wear protection, smooth shifting, fuel efficiency gains, and breakdown resistance for heavy-duty use.
• Suitable for automatic gearboxes in trucks and buses, some manual transmissions, hydraulic systems in earth-moving equipment, and power steering.
• Meets specs like MAN 339 Z-2/V-2, MB 236.8, GM Dexron IIE, Ford Mercon, Allison C-4, ZF TE-ML 04D.

When to Use / Replace?

Use Valvoline Heavy Duty ATF Pro in heavy-duty automatic transmissions requiring Dexron IIE or Mercon specs, especially for demanding fleet operations. Replace every 80,000-120,000 km or 24-36 months under normal conditions, or sooner (every 40,000 km) in severe duty like towing or extreme temps to prevent slippage and overheating.

Shelf life is 5 years unopened when stored cool and dry. Check fluid level and condition monthly; dark color or burnt smell means immediate replacement.
