Synthetic oil for ZF Lifeguard Fluid 8 automatic transmission, volume 6 liters

Synthetic Oil for ZF Lifeguard Fluid 8 Automatic Transmission, Volume 6 L

The original ZF Lifeguard Fluid 8 transmission fluid was developed by ZF Friedrichshafen AG specifically for modern multi-speed automatic transmissions of the 8HP series, as well as certain gearboxes of the 6HP series. The fully synthetic composition based on high-purity hydrocracked base oils and an advanced additive package guarantees optimal friction, silent gear shifting, and reliable protection of the hydraulic block from wear. Using the original oil eliminates slipping of friction discs, prevents sludge formation, and extends the transmission's life under high thermal and mechanical loads.

The product is supplied in a convenient format of a set of 6 plastic canisters, each with a volume of 1 liter. This volume is optimally sufficient for full or partial transmission service depending on the specific vehicle's design. The oil has excellent flowability at negative temperatures, ensuring easy engine start and instant filling of hydraulic channels in the automatic transmission in winter.

Application Features, Dosage, and Maintenance

Replacing ZF Lifeguard Fluid 8 transmission fluid requires strict adherence to the manufacturer's specifications. Adhering to dosage rules and filling procedures is critically important for the correct operation of the hydraulic system:

• For standard partial replacement of transmission oil in ZF 8HP gearboxes, usually 4.5 to 6 liters of fluid is required (depending on the transmission model and the sump-filter volume).

• In the case of a full hardware fluid replacement or after a major overhaul of the automatic transmission, the filling volume may range from 8 to 10 liters.

• Oil level control and correction are performed exclusively using a diagnostic scanner at a transmission fluid temperature of +30 °C to +50 °C with the engine running and the selector in the Park position.

• Overfilling or underfilling of fluid leads to oil foaming, harsh gear shifts, and accelerated wear of friction components, so the exact volume is adjusted via the control plug.

Detailed Compatibility with Cars and Transmissions

The fluid is fully adapted for ZF automatic transmissions of the 8HP series (8HP45, 8HP50, 8HP55, 8HP70, 8HP75, 8HP90), as well as 6HP (6HP19A, 6HP28AF).
