6HP is ZF Friedrichshafen AG's trademark name for its 6-speed automatic transmission models (6-speed transmission with Hydraulic converter and Planetary gearsets) for longitudinal engine applications, designed and built by ZF's subsidiary in Saarbrücken. Released as the 6HP 26 in 2000, it was the first 6-speed automatic transmission in a production passenger car. Other variations of the first generation 6HP in addition to the 6HP 26, were 6HP19, and 6HP 32 having lower and higher torque capacity, respectively. In 2007, the second generation of the 6HP series was introduced, with models 6HP 21 and 6HP 28. A 6HP 34 was planned, but never went into production.[1]
The last 6HP automatic transmission was produced by the Saarbrücken plant in March 2014 after 7,050,232 units were produced.[2][3] The ZF plant in Shanghai continued to produce the 6HP for the Chinese market.[2]
