Structure  

The electrical control unit (Y3/6) consists of a supporting body made from plastic, in which the electrical 
components, RPM sensors 2 and 3 (Y3/6n2, Y3/6n3), the regulating solenoid valves (Y3/6y1, Y3/6y2), the shift 
solenoid valves (Y3/6y6), the starter lockout contact (Y3/6s1) and transmission oil temperature sensor (Y3/6b1) 
are combined. See Fig. 35. Conductor tracks integrated into the shell connect the electric components to a plug 
connection (11).

The connection to the wiring harness on the vehicle side and the ETC control module (N15/3) is made via this 
13-pin connector (11) with a bayonet lock. 

With the exception of the solenoid valves, all other electric components are fixed to the conductor tracks.
