Purpose and Specifications

ZF LifeGuardFluid 8 ATF (part number 5961.308.143) is a premium automatic transmission fluid designed specifically for ZF 8-speed transmissions in cars from 2009 to 2025. This 1-liter bottle delivers smooth shifting, protects against wear, and maintains performance in everyday driving and heavy loads.

It flows easily in cold starts down to -42°C pour point for quick engagement, stays stable up to 206°C flash point during hot traffic or towing, and handles extreme heat over 280°C without breaking down. Fully synthetic formula ensures long-lasting lubrication, reducing friction for better fuel efficiency and quieter operation.

• Volume: 1 liter bottle, perfect for partial or full fluid changes
• Compatibility: ZF 8HP series (like 8HP50), matches OEM specs like G 060 162 A2
• Shelf life: 5 years unopened when stored cool and dry

When to Use / Replace?

Use this fluid for service fills or complete drain-and-fill in ZF automatic transmissions. Replace every 150,000 km (93,000 miles) under normal driving, or every 70,000 km (42,000 miles) for towing, high temps, or severe use to prevent slipping and overheating.

Ideal for vehicles with engines from 136 to 635 hp, ensuring reliable performance in daily commutes or long hauls.
