ZF 4HP transmission

The 4HP is a four-speed Automatic transmission family with a hydrodynamic Torque converter with an electronic hydraulic control for passenger cars from ZF Friedrichshafen AG. In selector level position "P", the output is locked mechanically. The Simpson planetary gearset types were first introduced in 1980, the Ravigneaux planetary gearset types in 1984 and produced through 2003 in different versions and were used in a large number of vehicles.

1984: Ravigneaux Planetary Gearset Types

The 4HP 14 was introduced in 1984 and produced through 2001 for Citroën, Peugeot, and Daewoo Front-wheel drive vehicles. The electronic-hydraulic control makes controlled power shifts and various shift programs possible.

The 4HP 16 is designed for use in vehicles with Front-wheel drive and a Transverse engine. The transmission is operated via selector lever and possibly also via switch. It has a controller slip Lock-up clutch.

The 4HP 18 is for both longitudinal and transverse installation. Introduced in 1987, and produced through 1998, it was used in a variety of cars from Alfa Romeo, Audi, Citroën, Dodge, Eagle, Fiat, Lancia, Porsche and Saab.
