5HP is ZF Friedrichshafen AG's trademark name for its five-speed automatic transmission models (5-speed transmission with Hydraulic converter and Planetary gearsets) for longitudinal engine applications, designed and built by ZF's subsidiary in Saarbrücken.

Specifications

Final Conventionally Designed Gearbox

With planetary gearboxes, the number of gears can be increased conventionally by adding additional gear sets as well as brakes and clutches, or conceptually by switching from serial to parallel power flow. The conceptual way requires a computer-aided design.

The 5HP is the last transmission family with serial power flow. To provide more gears, components were added. This makes these transmissions larger, heavier and even more expensive to manufacture. As the presence of ten main components (together with brakes and clutches) in the Ravigneaux gearbox types shows, this meant the end of the conventional gearbox design. The all new Lepelletier gearset concept of the later 6HP-family, requiring only eight main components for six gears, reflects the progress that this new paradigm represented.
