The 6-speed automatic gearbox ZF 6HP19 /A (09 ) has been installed on RWD and AWD BMW models, as well as on FWD and AWD Audi models (as 6HP19A). This transmission can be paired with engines with capacity up to 3.5 liters. ZF 6HP19 was constructed jointly with ZF6HP26 as a “light” modification. Aisin’s TR-60S and VW's DSG-6 are considered the main competitors of this ZF unit. VAG is the main user of ZF transmission solutions. In 2006, ZF released 6HP21 and 6HP28 modifications. These two units have the same new Mechatronic unit of the 2nd generation with improved gear shifting mechanism. ZF engineers also improved the valve body, replaced solenoids, replaced some friction elements and almost all steel plates

Technical issues and repair guidelines

ZF recommends changing ATF in this transmission no later than after covering 100 thousand kilometers or after 8 years of running under the condition of "careful" driving style. The amount of required ATF for a full change is 9.5 L. This gear shifting unit operates with any good quality fluid such as Dexron VI. It is advisable to make two partial fluid changes in case of contaminated fluid and at the same time to change the filter.


Transmission specialists usually replace solenoids when the car with this transmission reaches high mileages and problems with gear shifting. The torque converter is also rebuilt in the process solenoid replacement.The complete reassembly includes removal of the transmission unit, and order of the repair kit of gaskets and seals. In the process of reassembly, the whole set of friction components is replaced, especially when ATF gets burned. The full kit of bushings is replaced as well.


Typical problems of ZF 6HP19-21

The most common problem for powerful cars equipped with this transmission is the torque converter. Its locking mechanism became regulated and forced from the first gear.The main problem of 6HP19\21 – is the Mechatronic unit. Electronic components are sensitive to temperature drops and falls– too high and too low oil temperatures as well as the presence of metal chips are undesirable factors for this transmission.The main spare part of 6HP valve body became the separator plate of the valve body.


Structural peculiarities of this gear shifting unit (vibrations of torque converter and pump stator, operating with oil shortage...) lead to fast wearing of bushings.The wear of bushings results in pressure losses in corresponding packages and the control unit opens electromagnetic valves of solenoids more and more in order to compensate oil shortages. Common replacement part – the pump seal, and less frequently - output shaft seal. Transmission specialists frequently replace worn pump bearings.


The main problem for the 6HP19 unit in winter time is replacement of the adapter to the block of solenoids (also called as “Sleeve”). It is recommended to replace the “Sleeve" within the framework of the sheduled repair without waiting for its damage. The common spare part in summer time is the adapter to mechatronics. This adapte, included in some repair kits, has a short service life and recommended for change each 2-4 years. With this repair part, it is also advisable to replace sealing tubes of the valve body.
