ZF 8HP Transmission Retrofit for Mercedes G-Class
Modern 8-speed automatic upgrade for classic G-Class platforms. Efficiency, control and drivability.
ZF 8HP Retrofit Platform
The ZF 8HP transmission retrofit transforms how the G-Class drives. It introduces modern shifting behavior, improved efficiency and refined control while retaining the mechanical foundation of the platform.
Overland-G ZF 8HP Architecture
The ZF 8HP 8-speed automatic transmission is a central part of the Overland-G Momentum drivetrain architecture.
It brings modern shift quality, improved cruising efficiency and stronger drivability to earlier Mercedes G-Class platforms while preserving the mechanical character that makes the platform valuable.
Why ZF 8HP
- Modern 8-speed automatic drivability
- Improved highway cruising and reduced engine RPM
- Strong torque handling for diesel expedition builds
- Controlled low-speed behaviour for off-road use
- Standalone electronics integration
Integrated, Not Added
In Overland-G Momentum, the ZF 8HP is not treated as an isolated gearbox swap. It is part of a wider drivetrain architecture including diesel engine selection, cooling, transfer case integration, electronics and vehicle use case.
The ZF 8HP delivers smooth gear transitions and optimized ratios, reducing engine load and improving long-distance driving performance.
Conversion Architecture
Integration requires engine adapters, transfer case adapters, standalone control systems and dedicated cooling solutions to ensure full compatibility.
Driver Experience
The retrofit significantly improves daily usability, combining off-road control with modern automatic transmission comfort and precision.
