GF27.19-P-5145AHI Electric controller unit, component description
- TRANSMISSION 722.930

Component Identification:

Location
The electric controller unit (VGS), valve housing, intermediate panel and valve body are joined together by means of bolts. The electric controller unit (VGS) is installed under the transmission housing and is constantly flushed by transmission oil for cooling.

Design
The electric controller unit (VGS) has a plastic supporting body and contains the following components:

- Start-up clutch oil pressure sensor (Y3/8b1)
- Turbine speed sensor (VGS) (Y3/8n1)
- Internal speed sensor (VGS) (Y3/8n2)
- Output speed sensor (VGS) (Y3/8n3)
- Fully integrated transmission control (VGS) control unit (Y3/8n4) with integrated transmission oil temperature sensor (VGS) (Y3/8s2)
- Selection range sensor (VGS) (Y3/8s1)
- Working pressure control solenoid valve (VGS) (Y3/8y1)
- K1 clutch control solenoid valve (VGS) (Y3/8y2)
- K2 clutch control solenoid valve (VGS) (Y3/8y3)
- K3 clutch control solenoid valve (VGS) (Y3/8y4)
- B1 brake control solenoid valve (VGS) (Y3/8y5)
- B2 brake control solenoid valve (VGS) (Y3/8y6)
- B3 brake control solenoid valve (VGS) (Y3/8y7)
- Y3/8y9 Start-up clutch control solenoid valve

The conductor track film which is inserted in the supporting body makes the connection between the electrical components and the 6-pin plug coupling.

Apart from the solenoid valves all the other electrical components are permanently connected to the printed-conductor foil. The connection to the cable set at the vehicle end is made with a bayonet lock via a 6-pin plug coupling.
