Chronology | |
Predecessor | ZF 5HP Transmission |
Successor | ZF 8HP Transmission |
6HP is ZF Friedrichshafen AG's trademark name for its six-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 six-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.
The 6HP uses a Lepelletier epicyclic/planetary gearset, which can provide more gear ratios with significantly fewer components. This means the 6HP 26 is actually lighter than its five-speed 5HP predecessors. It also has the capability to achieve torque converter lock-up on all six forward gears, and disengage it completely when at a standstill, dramatically closing the fuel efficiency gap between automatic and manual transmissions.
The last 6HP automatic transmission was produced by the Saarbrücken plant in March 2014 after 7,050,232 units were produced.[1][2] The ZF plant in Shanghai continued to produce the 6HP for the Chinese market.[1]
Specifications
Preliminary Note
All ZF 6HP gearboxes have the same gear ratios as the 6R60 and 6R80 gearboxes for passenger cars from Ford. Deviant gear ratios indicate another manufacturer as shown in the template.
New Paradigm
The 6HP is the first transmission designed according to ZF's new paradigm. After gaining additional gear ratios only with additional components, this time the number of components has to decrease for the first time in spite of the necessity of even more ratios. Coming from 5 gear ratios made of 10 main components (gear sets, Ravigneaux considered as 2, brakes, clutches) to the 6 made of 8 now reflects, what major progress the Lepelletier gear mechanism means compared to conventional designs like the 5HP-family.

Technical imperfections
Problems with this transmission are well known. This transmission locks up the torque converter in all gears, increasing wear. Combined with a sealed transmission pan and "lifetime fluid", some people have experienced catastrophic transmission failure. Owners report shift issues when oil begins breaking down beyond 50K miles, hence shifting issues are common.
There are also problems with the valve block and solenoids When this failure starts to occur, shift quality and speed, torque transfer and even loss of ability to engage gears can occur. These problems led Volkswagen Group to extend the warranty on all of their vehicles equipped with this transmission to 100,000 miles or 10 years.
