1 - Sensor 3 revolutions (Y3/6n3); 2 - Solenoid valve for modulating pressure adjustment (Y3/6y1); 3 - Sensor 2 revolutions (Y3/6n2); 4 - Temperature sensor input (Y3/6b1) and starter interlock contact (Y3/6s1); 6 - Supply voltage e / magnetic valves; 7 - Sensor supply voltage; 8 - E / magnetic valve for shifting gears 2-3 (Y3/6y5); 9 - E / magnetic valve for shifting gears 3-4 (Y3/6y4); 10 - Solenoid valve for adjusting the switching pressure (Y3/6y2); 11 - E / magnetic valve (rotation transducer blocking) (Y3/6y6); 12 - Sensor body; 13 - Solenoid shift valve 1-2/4-5 (Y3/6y3)
TCM (N15/3) determines the current operating parameters of the vehicle and performs sequential shift control based on the ease of shifting and driving parameters.
Activation of the switching solenoid valves is carried out at the command of the ETC control unit (N15/3). The required pressure value is calculated on the basis of the input data and the necessary correction adjustment of the transmitted torque.
