Purpose and Specifications

ZF LifeGuardFluid 5 is a premium automatic transmission fluid engineered specifically for ZF 4HP20 and 5HP automatic transmissions. This semi-synthetic fluid delivers smooth, vibration-free shifting while protecting all internal transmission components from wear and heat damage.

Key Performance Features:

• Optimized friction behavior for perfect shift quality and comfort
• Works reliably in extreme temperatures: from -51°C (cold climates) to 220°C (operating heat)
• Advanced additives protect transmission gears, clutches, and seals throughout the fluid's service life
• High thermal stability maintains performance even under demanding driving conditions
• Tan color, 20-liter canister format

When to Use / Replace?

Follow your vehicle manufacturer's service schedule, typically every 40,000 to 80,000 kilometers or 2 to 4 years, whichever comes first. Check your owner's manual for exact intervals. Use only ZF LifeGuardFluid 5 for your compatible ZF transmission—mixing fluids can damage shifting performance and reduce component lifespan.
