Purpose and Specifications

RAVENOL ATF 5/4 HP 4L is a fully synthetic automatic transmission fluid designed for ZF 4-speed (4HP20, 4HP22, 4HP24) and 5-speed (5HP18, 5HP19, 5HP24, 5HP30) transmissions. It meets key specs like MB 236.11, VW G 055 162, VW TL 521 62, Renault DP0, ATF LT 71141, and ATF LA 2634, ensuring smooth shifts and maximum wear protection in everyday driving.

This mid-range oil flows easily in cold winter starts down to -30°C for quick lubrication, stays thick up to 150°C to protect clutches and bands during hot traffic or towing, and resists oxidation for long-term reliability. Its balanced friction reduces slippage, cuts fuel use, and prevents foam or corrosion for quieter, cooler operation.

When to Use / Replace?

Use RAVENOL ATF 5/4 HP in compatible ZF automatics for maintenance refills under normal conditions. Replace every 60,000-100,000 km or 4-5 years, or sooner if towing heavy loads or in severe heat/dust. Shelf life is 5 years unopened in cool storage.

• Check fluid level and color (natural brown) monthly.
• Flush if dark or burnt-smelling to avoid shift issues.
• Ideal for BMW, Land Rover Discovery 2, VW/Audi, and Mercedes with these ZF units.
