Operation
The shift pressure (p-S) is determines by the shift pressure regulating solenoid valve (Y3/6y2) and the shift
pressure regulating valve (24). See Fig. 177. In addition, pressure from the multiple-disc clutch K2 (p-K2) is
also present at the annular surface (24a) of the shift pressure regulating valve (24). This reduces the shift
pressure in 2nd gear.

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). See .Fig. 179
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 planetary gear carrier via the
inner multiple-disc carrier of the front multiple-disc clutch (K1c).
