- The 1st-Reverse position sensor 1 and 1st-Reverse position sensor 2 are installed on the actuator control valve and detect the sleeve B1 position.
- The 1st-Reverse position sensor 1 and 1st-Reverse position sensor 2 convert the sleeve B1 position into output voltage and transmit the signal to TCM.
- The sleeve B1 has its oil passage secured by the shift solenoid valve 3 and shift solenoid valve 2 when the sequence solenoid valve is OFF and is driven by the axis B feed pressure solenoid valve. The 1st gear and reverse gear are selected or deselected depending on the operation of the sleeve B1.
