ZF 4HP transmission

(Redirected from ZF 4HP20 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.

1980: Simpson Planetary Gearset Types edit

The 4HP 20 was introduced in 1995 and has been used in a variety of cars from Citroën, Lancia, Mercedes-Benz, Peugeot, and Renault.[1] The maximum torque capacity is 330 N⋅m (243 lb⋅ft).

The 4HP 22 was produced for vehicles with rear wheel drive or 4X4 layout. Introduced in 1980, it was produced through 2003, and has been used in a variety of cars from BMW, General Motors, Jaguar, Land Rover, Maserati, Peugeot, Porsche, and Volvo.

The 4HP 24 was introduced in 1987 and was used in a variety of cars from Audi, BMW, Jaguar, and Land Rover.

1984: Ravigneaux Planetary Gearset Types edit

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.
