05–17–36 AUTOMATIC TRANSAXLE SHIFT SOLENOID A, B AND C (DUTY-CYCLE TYPE) OUTLINE B3E051721100A02 • The clutch pressure direct control, which supplies the clutch pressure directly to each clutches and/or brake, is adopted. The three-way duty-cycle type solenoids with excellent controllability are adopted, to improve End Of Sie SHIFT SOLENOID A, B AND C (DUTY-CYCLE TYPE) FUNCTION B3E051721100A03 • The duty-cycle type shift solenoid adjusts the amount of output pressure according to the signal from the PCM, and controls the pressure of each clutch. • The duty-cycle type shift solenoid, which switches ON/OFF at 50 Hz (20 ms cycle) and controls the . End Of Sie SHIFT SOLENOID A, B AND C (DUTY-CYCLE TYPE) OPERATION B3E051721100A04 OPEN:When the electrical current does not flow, the supply port (line pressure) in the solenoid opens and is engaged with the output port (clutch pressure). As a result, hydraulic pressure is supplied to the hydraulic CLOSE:When the electrical current flows, the supply port (line pressure) in the solenoid closes and the output port (clutch pressure) and the drain port are engaged to drain the clutch pressure. . 3 1 2 B3E0517T035 1 Output port (clutch pressure) 2 Supply port (line pressure) 3 Drain 5 4 3 1 2 3 B3E0517T036 1 Electrical current does not flow (OPEN) 2 Electrical current flows (CLOSE) 3 Output port (clutch pressure) 4 Supply port (line pressure) 5 Drain |
