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); 5 -; 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)
The TCM detects the vehicle's current operating parameters and manages sequential shifting based on ease of shifting and driving parameters.
Shift solenoid valves are activated by the TCM. The required pressure value is calculated on the basis of the input data and the necessary correction adjustment of the transmitted torque.
