Purpose and Specifications

ORLEN HIPOL ATF II D is a premium mineral automatic transmission fluid designed for passenger cars, trucks, and buses that require GM Dexron II D specification oil. This fluid serves multiple critical functions in your vehicle's transmission and hydraulic systems.

The oil performs four essential jobs: it lubricates transmission gears to reduce friction and wear, transmits hydraulic pressure to control gear shifts smoothly, dissipates heat generated during operation, and protects metal components from corrosion and rust. The fluid also keeps your transmission clean by removing deposits and impurities that accumulate over time.

Key Performance Data:

• Operates effectively from cold starts to high-temperature highway driving
• Flash point of 208°C ensures safety and stability under extreme conditions
• Excellent anti-wear protection with minimal component damage during operation
• Zero foam formation at both cold (25°C) and hot (95°C) temperatures, preventing air pockets that reduce hydraulic pressure
• Resists copper corrosion, protecting transmission valve bodies and hydraulic components

Compatible with: GM Dexron II D, Allison C-4, MAN 339 (Z1, V1, L2), ZF TE-ML (04D, 11A, 14A), Voith H55.6335xx, and other ATF II D-specification systems.

When to Use / Replace?

Check your vehicle's owner manual for the exact replacement interval, as this varies by manufacturer. Most automatic transmissions require fluid checks every 20,000–40,000 km or every 12 months, whichever comes first. Complete fluid changes typically occur every 60,000–100,000 km for normal driving conditions, though some modern vehicles may have longer intervals.

Replace the fluid immediately if it appears dark brown or black, smells burnt, or shows signs of contamination. Regular maintenance extends transmission life and prevents costly repairs.

This 1-liter canister is ideal for top-ups between service intervals or for vehicles with smaller transmission capacities.

Frequently Asked Questions

Q: Can I mix HIPOL ATF II D with other transmission fluids?
A: No. Always use the exact fluid specification your vehicle manufacturer recommends. Mixing different ATF types can damage seals, reduce hydraulic pressure, and cause transmission failure. If switching fluids, perform a complete fluid flush first.

Q: How do I know if my transmission needs fresh fluid?
A: Check the dipstick (if your vehicle has one) monthly when the engine is warm and parked on level ground. The fluid should be bright red and smell slightly sweet. Dark color, burnt smell, or low level indicates the need for service. Some vehicles require dealer diagnostics to check fluid condition.

Q: Is this oil suitable for power steering and hydraulic clutches?
A: Yes. HIPOL ATF II D is approved for power steering systems, hydraulic clutches in cars and trucks, and other ATF-specification hydraulic systems. Always verify your specific system's requirements in the owner manual before use.
