ZF LifeGuard Fluid 7.5 DCT - Premium Automatic Transmission Oil

Purpose and Specifications

ZF LifeGuard Fluid 7.5 DCT is a premium automatic transmission fluid engineered specifically for dual-clutch transmissions (DCT). This fluid maintains optimal performance in modern 7-speed dual-clutch gearboxes, ensuring smooth gear shifts, reliable power delivery, and extended transmission life.

Key Performance Features:

• Formulated for dual-clutch transmission systems requiring precise friction control
• Protects against wear and thermal breakdown during high-performance driving
• Maintains consistent viscosity across a wide temperature range, from cold starts to highway driving
• Reduces clutch slippage and ensures crisp, responsive gear changes
• Extends transmission service intervals through superior oxidation resistance

When to Use / Replace?

Replacement Schedule: Most dual-clutch transmissions using this fluid require service every 40,000 to 80,000 kilometers or 2 to 4 years, depending on driving conditions and manufacturer recommendations. Check your vehicle's service manual for exact intervals.

Operating Temperature Range: This fluid performs reliably between -30°C and +150°C, making it suitable for both cold winter starts and sustained high-speed driving.

When to Replace:

• During scheduled transmission service intervals
• If transmission shows delayed engagement or rough shifting
• After any transmission repair or fluid leak repair
• If fluid appears dark, burnt-smelling, or contaminated

Storage: Keep unopened bottles in a cool, dry location. Shelf life is typically 3 to 5 years when stored properly away from direct sunlight.
