Specialists In All Makes Of Dual-Clutch Transmission
ESTABLISHED SINCE 1991 WITH OVER 40 YEARS TRANSMISSION EXPERIENCE
A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission or double-clutch transmission) is an automated manual transmission in motor vehicles, closely related to a manual transmission. It uses two separate clutches for odd and even gear sets. It can fundamentally be described as two separate manual transmissions with their respective clutches contained within one housing, and working as one unit. Although usually operated in a fully automatic mode, all have the ability to manually shift using the transmissions electrohydraulics.
A dual-clutch transmission eliminates the torque converter as used in conventional epicyclic-geared automatic transmissions. Instead, dual-clutch transmissions that are currently on the market primarily use two oil-bathed wet multiplate clutches, though dry-clutch versions are also available.
MECHATRONIC UNITS & CODING
Mechatronic Units Tested
VW, AUDI, FORD, NISSAN, MERCEDES, VOLVO, MITSUBISHI ZF6/ZF8/ZF9.
A Mechatronic unit uses a combination of mechanical & electronic engineering. The unit consists of a valve body assembly with solenoids. The electronic control unit is usually attached to the valve body with exception of the Porsche PDK a dual-clutch transmission designed by ZF.
In most Mechatronic units with exceptions to the dry clutch units, the valve body section simulates the same design as the standard automatic transmission ie; Spool valves, Check valves, and Thermostatic bypass valves. Springs are also used to resist and control the movement of the valve.
SERVICING DUAL-CLUTCH TRANSMISSIONS
Servicing these transmissions is vital. They should be carried out at the manufacturer's service intervals. Essentially as the dual-clutch transmission is two manual gearboxes in one housing, the swaf generation is substantial. Swaf is collected around the selector fork's magnetic sensor pick-ups for selector position & around the speed sensor pickup ring.
Failure to keep this transmission maintained will result in an expensive failure. It is one of the reasons why the transmission control unit on an OAM 7spd dry clutch short circuits, as gear oil creeps in the back of the unit then BOOM! It needs a new unit.
