Original ZF lubricant from ATS
ZF Lifeguard Fluid 7.7 DCT — precision friction control for ZF dual-clutch systems
ZF Lifeguard Fluid 7.7 DCT is made for dual-clutch applications where the oil must support clutch control, hydraulic response and gear protection at the same time. It helps preserve crisp shift behavior and drivetrain refinement in selected ZF DCT systems where fluid specification is central to long-term performance.
High-performance dual-clutch transmission fluid for demanding Porsche and ZF transaxle configurations

Selected S7 and 7DT DCT applications where Lifeguard Fluid 7.7 DCT is explicitly listed
The cited TE-ML 11 DCT rows define where the fluid is approved, but do not publish one generic passenger-car interval for all 7DT / S7 service cases. ATS must confirm interval by exact unit and vehicle service specification.
Why Choose Original ZF Lifeguard Fluid 7.7 DCT
ZF frames the product as a high-performance DCT fluid for Porsche and ZF transaxle configurations requiring optimized gear protection.
- ZF warns that only explicitly released ATF should be used for service or top-off; off-the-shelf multi-vehicle ATF can create shift issues or kinematic degradation.
