5HP is ZF Friedrichshafen AG's trademark name for its 5-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.

The 5HP 18 and 19 are a transmission family with purely serial power flow: components were simply added to enable more gears. This makes these transmissions larger, heavier, and more expensive. With 10 main components, progress was unsatisfactory: an obvious transitional solution. It is therefore the last conventionally designed transmission from ZF. All subsequent transmissions from ZF including the 8-speed transmission 8HP require fewer main components.

The main objective in replacing the predecessor model was to improve vehicle fuel economy with extra speeds and a wider gear span to allow the engine speed level to be lowered (downspeeding).

With planetary transmissions, the number of gears can be increased conventionally by adding additional gearsets as well as brakes and clutches, or conceptually by switching from serial to combined parallel and serial power flow. The conceptual way requires a computer-aided design. The resulting progress is reflected in a better ratio of the number of gears to the number of components used compared to existing layouts.
The 5HP 30 and 24 are the first transmission family with combined parallel and serial power flow to prevent these transmission from becoming larger, heavier, and more expensive. With 9 main components, it saves 1 component compared to the 5HP 18 and 19 family. No subsequent transmissions from ZF including the 8-speed transmission 8HP require more main components.
