Motor vehicle
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
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
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 .
