Function

In the electric controller unit (VGS) (Y3/8) signals from the fully integrated transmission control (VGS) control unit (Y3/8n4) are converted into hydraulic functions. The following electrical components supply input signals to the fully integrated transmission control (VGS) control unit (Y3/8n4):

Turbine speed sensor (VGS) (Y3/8n1)
Internal speed sensor (VGS) (Y3/8n2)
Output speed sensor (VGS) (Y3/8n3)
Transmission oil temperature sensor (VGS) (Y3/8s2) integrated into the fully integrated transmission control (VGS) control unit (Y3/8n4)
Selection range sensor (VGS) (Y3/8s1)
The control solenoid valves listed are actuated by the fully integrated transmission control (VGS) control unit (Y3/8n4) and trigger the hydraulic functions:
Working pressure control solenoid valve (VGS) (Y3/8y1)
Clutch control solenoid valve K1 (VGS) (Y3/8y2)
Clutch control solenoid valve K2 (VGS) (Y3/8y3)
Clutch control solenoid valve K3 (VGS) (Y3/8y4)
Brake control solenoid valve B1 (VGS) (Y3/8y5)
Brake control solenoid valve B2 (VGS) (Y3/8y6)
Brake control solenoid valve B3 (VGS) (Y3/8y7)
Torque converter lockup clutch control solenoid valve (VGS) (Y3/8y8)
