  1. Installation is the reverse of removal.
  2. After assembling, check the followings. When shifting with each position, lever must be operated securely without friction and free from looseness, noise and so on. When lever shifting, it shall not be stopped easily between each positions. When lever should be stopped between "P" and "R" position intentionally. It should not be shifted to "R" position by vibration added for lever assembly. Free from noise when being shifted from "R" to "N", push button being released. Slider must be operated smoothly between each position. Slider must be operated smoothly without looseness, sticking and noise. Shift lock must be operated well.

DESCRIPTION

The pulse generator "A" detects the speed of the end clutch retainer. The speed signal is used for damper clutch control, hydraulic pressure control and incorrect gear detection by PCM.

The pulse generator "B" detects the speed of the transfer driven gear. The speed signal is used for shift timing, hydraulic pressure control and incorrect gear detection by PCM.

Pulse generator A, BInspection itemStandard value
Sensor resistanceA: 1 terminal ~ 2 terminal215 ~ 275 ohms
B: 1 terminal ~ 2 terminal215 ~ 275 ohms
Output voltage (A, B)1 terminal ~ ground2.5 V ± 1.2V
2 terminal ~ ground2.5 V

  3. Disconnect the sensor wire from the control cable mounting bracket.
  4. Remove the pulse generator A, B. Disconnect the connector from the sensor. Measure the pulse generator A, B resistance. Standard value: Pulse generator A: 245±30ohms/20°C (68°F) Pulse generator B: 245±30ohms/20°C (68°F) If the result isn't within the standard value, remove the pulse generator A, B.
  5. Measure the pulse generator A, B resistance. Standard value Pulse generator A : 245±30ohms/20°C (68°F) Pulse generator B : 245±30ohms/20°C (68°F)
  6. If the result isn't within the standard value, replace the pulse generator A, B.
  7. Apply the ATF oil around the oil seal before installing the oil seal.
  8. Install the pulse generator A, B. TORQUE : 10~12Nm (100~120Kgf.cm, 7~8lb-ft)
  9. Connect the sensor wire to the control cable mounting bracket.
  10. Connect the pulse generator connector.
  11. Installation is the reverse of removal.

The oil temperature sensor (A) detects the automatic transaxle fluid temperature. The oil temperature sensor is a negative thermal coefficient type. The resistance of the sensor increases when the oil temperature goes down and the resistance goes up when the oil temperature decreases.

Using the signal from this sensor, PCM corrects the solenoid drive duty when the fluid is cold (lower than 60°C) and hot (higher than 125°C). PCM restricts the shift pattern to the economy mode when the fluid is cold.- Service point

  6. If the result isn't within the standard value, remove the valve body cover.
  7. Replace the fluid temperature sensor (A).

When the selector lever is in the position other than "P" or "N", the electrical circuit for starting the engine is kept in the OFF state by the inhibitor switch. Therefore, the engine does not start even if the ignition switch is turned to the "START" position. Inhibitor switch is installed on the transaxle case located at the upper end of the manual control shaft and is interlocked with the manual control lever.

By shifting the selector to the "P" or "N" range, the electrical circuit inside the inhibitor switch is connected to form the ignition circuit with which the engine can be started. When the shift is in the "R" range, the backup lamp lights up as backup lamp circuit is energized.

The inhibitor switch, in addition to the start safety device, also includes a circuit for detection of the selector lever position, for sending signals to the transaxle control module.
