Original ZF lubricant from ATS
ZF Lifeguard Fluid 7.3 DCT — the fluid behind fast, clean dual-clutch shifts
Dual-clutch transmissions depend on a fluid that can manage friction, pressure and heat with very little margin for error. ZF Lifeguard Fluid 7.3 DCT is positioned for selected ZF DCT applications, supporting precise clutch engagement, stable hydraulic performance and the component protection required in compact high-response drivetrains.
Dual-clutch transmission fluid for high-pressure wet clutch actuation and compact gear-train lubrication

Selected S6 dual-clutch systems and 7DT DCT applications where Lifeguard Fluid 7.3 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The cited TE-ML 11 DCT rows define where the fluid is approved, but do not publish one generic passenger-car interval for all 7DT / S6 service cases. ATS must confirm interval by exact unit and vehicle service specification.
Why Choose Original ZF Lifeguard Fluid 7.3 DCT
ZF frames the product as a dual-clutch fluid that must manage both wet-clutch actuation and gear-train lubrication in DCT architectures.
- 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.
