Operation
The RPM sensors are pressed against the transmission housing (51) by a spring (49) which is held against the valve housing of the shift plate (2a). This ensures a defined distance between the RPM sensors and the exciter ring (50).
RPM sensor 2 (Y3/6yn2) records the speed of the front sun gear via the outer multiple-disc carrier of the front multiple-disc clutch (K1b) and RPM sensor 3 (Y3/6yn3) records the speed of the front planetary gear carrier via the inner multiple-disc carrier of the front multiple-disc clutch (K1c).
