Mercedes G Class ZF8HP Oil Cooler Kit

G-Class ZF 8HP Transmission Cooling System

The ZF 8HP Transmission Oil Cooling Kit manages thermal load in Mercedes G-Class builds using the ZF 8HP automatic transmission.

Thermal Control

Automatic transmissions generate significant heat, especially during low-speed driving, off-road operation and high torque load conditions. This system maintains stable oil temperatures to support consistent transmission performance.

System Function

The cooling kit provides a dedicated circuit for transmission oil, reducing heat buildup and protecting internal components from thermal stress.

Performance Stability

Maintaining controlled oil temperature helps preserve shift quality, reduces wear and supports long-term reliability of the gearbox under demanding conditions.

Integration

The system is designed to operate together with engine cooling and intercooling solutions as part of a complete drivetrain thermal management setup.

It is used within the ZF 8HP Transmission Swap Kit as part of the full conversion architecture.

Configuration

Cooling layout and component selection may vary depending on engine configuration, vehicle generation and overall build setup.

Compatibility

Compatible with Mercedes G-Class platforms W460, W461 and W463 equipped with ZF 8HP transmission conversions. Configuration should be confirmed before ordering.

Application

Used in builds where transmission temperature control is required under sustained load, high ambient temperatures or limited airflow conditions.
