Pressure sensor | Clutch A pressure sensor | Converts the clutch pressure of clutches A/B into voltage |
Clutch B pressure sensor
Actuator control module | Valve | Axis A feed pressure solenoid valve | Controls the feed pressure of axes A/B by the axes A/B feed pressure solenoid |
Axis B feed pressure solenoid valve
Shift solenoid valve 1 | Controls 4 shift actuator pistons by combining ON and OFF of each shift solenoid valve*1
Shift solenoid valve 2
Shift solenoid valve 3
Shift solenoid valve 4
Sequence solenoid valve
Pressure sensor | Line pressure sensor | Converts the line pressure into voltage |
Position sensor | 1st-Reverse position sensor 1 |

- Converts each shift actuator position into voltage
- Two 1st-reverse position sensors with the same output (but the output characteristics are inverse) are installed for fail-safe

1st-Reverse position sensor 1
2nd-4th position sensor
6th-Neutral position sensor
3rd-5th position sensor
Wheel sensor | Clutch A speed sensor | Converts the clutches A/B speed into pulse
Clutch B speed sensor
Output shaft speed sensor | Converts the output shaft speed into pulse
Park position switch | When the parking position is locked, it is energized, and when unlocked, it is not energized
Fluid temperature sensor | Converts the oil pan oil temperature into electrical resistance |
TCM | Controls the transmission system
Shift device | Range sensor | Range sensor No. 0 | With 6 range sensors, the shift lever position is recognized*2
Range sensor No. 1
Range sensor No. 2
Range sensor No. 3
Range sensor No. 4
Range sensor No. 5
Auto/Manual range change switch | Inputs the Auto/Manual range change switch signal to TCM
Shift lock solenoid | Lock or unlock is attained with 3 systems, the ignition switch signal, stop lamp switch signal and lock or unlock signal (TCM)
Set-up switch | R mode switch | Normally not energized, and energized by turning the set-up switch to R
SNOW mode switch | Normally not energized, and energized by turning the set-up switch to SNOW
TCM relay | Perform the power supply to TCM
