Transmission general data

The main constructive idea for shifting gears in DCT WD is adopted from n-speed transmissions and the shifting is performed by means of hydraulics and solenoids controlled by the control unit. Therefore many age-related problems are the same as n-speed transmissions: metal friction suspended material from hot ATF clogs valves of the valve body and solenoids, gets on the rubbing surfaces and promotes the wear of aluminum by vibrations and sticking of valves, especially when the friction clutches are worn out, that leads to a chain reaction of metal wear and further contamination of oil.

Therefore the 6DCT450 has more capacious outside filter in comparison with other CVTs. There are several filters-cartridges modifications, which are different for DCT450 and DCT470. The filter is included in the overhaul repair kit, but Gertrag engineers recommend to replace this filter more often, especially if the transmission has been used for a long time.

Technical issues and repair guidelines

For the DCT450 transmission reassembly, specialists order the repair kit of gaskets and seals. Repair kits contain gaskets (required as a minimum), which affect the operation of this delicately adjusted transmission. The wearout of Teflon rings also has a major impact on the transmission operation. Replacement of the filter with ATF is a typical repair procedure recommended for maintenance of WD Powershift transmissions. It is advisable to change oil more often and not later than after 45-50 thousand kilometers.


For the overhaul of 6DCT450 it is common to replace solenoids in order to solve problems with the valve body. The overhaul of the clutch basket in 6DCT450 is accompanied by order of springs and retainers-clips. When the dry clutch gets out of order specialists have to replace the step motor or more frequently the transmission itself
