Odd Gear Clutch Slave Cylinder – Alfa Romeo TCT

The odd gear clutch slave cylinder (CSC) hydraulically operates the clutch responsible for the odd gears in the 6-speed TCT dual-clutch transmission. Hydraulic pressure moves an internal piston, which actuates the clutch release bearing through a push rod running inside the transmission shafts. An integrated Hall effect sensor monitors the piston position, allowing the transmission control unit to precisely control clutch engagement and disengagement. A defective slave cylinder can cause clutch engagement problems, gear shifting faults or transmission error messages.
