Motor vehicle automatic transmission models
From Wikipedia, the free encyclopedia
The 4HP is a 4-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.
