WARNING: This page is about a different variant/trim than selected.
The gearshift functions of the 6DCT250 can be divided into a clutch system and a gearshift system. The TCM controls the clutch and gearshift system with the aid of the four brushless DC motors with integrated position sensors.
The corresponding DC motor is actuated both during clutching and during the gearshift. The information about the position of the DC motors is sent via the integrated position sensors to the TCM. On the basis of this information, the TCM knows which gears are engaged and which clutch the power flow is routed through.
