As such, the 6HP19 is rated at 400 N⋅m (295 lb⋅ft) of torque. The 6HP19 transmission was a development of the original 6HP26, but was downgraded for less demanding applications. These problems led Volkswagen AG to extend the warranty on all of their vehicles equipped with this transmission to 100,000 miles or 10 years. When this failure starts to occur, shift quality and speed, torque transfer and even loss of ability to engage gears can occur. There are also problems with the valve block and solenoids. Owners report shift issues when oil begins breaking down beyond 50K miles, hence shifting issues are common. Combined with a sealed transmission pan and "lifetime fluid", some people have experienced catastrophic transmission failure. This transmission locks up the torque converter in all gears, increasing wear. Problems with this transmission are well known. 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. 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.
The 6HP is the first transmission designed according to ZF's new paradigm. Deviant gear ratios indicate another manufacturer as shown in the template. Specifications Preliminary Note Īll ZF 6HP gearboxes have the same gear ratios as the 6R60 and 6R80 gearboxes for passenger cars from Ford have. The ZF plant in Shanghai continued to produce the 6HP for the Chinese market. The last 6HP automatic transmission was produced by the Saarbrücken plant in March 2014 after 7,050,232 units were produced. 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. This means the 6HP26 is actually lighter than its five-speed 5HP predecessors. The 6HP uses a Lepelletier epicyclic/planetary gearset, which can provide more gear ratios with significantly fewer components. A 6HP34 was planned, but never went into production.
Repair manual zf 6hp19 series#
In 2007, the second generation of the 6HP series was introduced, with models 6HP21 and 6HP28. Other variations of the first generation 6HP in addition to the 6HP26, were 6HP19, and 6HP32 having lower and higher torque capacity, respectively.
Released as the 6HP26 in 2000, it was the first six-speed automatic transmission in a production passenger car. 6-Speed Longitudinal Automatic TransmissionĪisin AWTF-80 SC Transmission Ford 6R Transmissions GM 6L50 Transmission GM 6L80 TransmissionĦHP 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.
