[23A] AUTOMATIC TRANSMISSION (FF) - - ON-VEHICLE SERVICE - A/T CONTROL COMPONENT CHECK - A/T CONTROL SOLENOID VALVE ASSEMBLY CHECK | PRINT PAGE / INDEX / PRIOR / NEXT

| A/T CONTROL SOLENOID VALVE ASSEMBLY CHECK Use the MUT-II/III to measure the A/T fluid temperature and check that the A/T fluid temperature is 20°C.
| Disconnect the A/T control solenoid valve assembly connector. Measure the resistance between the solenoid valve terminals. Check that the measured values are within the standard values at items 1 and 3.
Standard value:
Name | Terminal No. | Resistance value
--- | --- | ---
Damper clutch control solenoid valve | 7 - 10 | 2.7 - 3.4 Ω (A/T fluid temperature 20°C)
Low-reverse solenoid valve | 6 - 10
Second solenoid valve | 4 - 9
Underdrive solenoid valve | 3 - 9
Overdrive solenoid valve | 5 - 9
Reduction solenoid valve <5A/T> | 8 - 10
If within the standard value, check the power supply and the earth circuits. If not within the standard value, drain the A/T fluid and remove the valve body cover.
| Disconnect the solenoid valve connectors.
| Measure the resistance between terminals 1 and 2 at each solenoid valve side. Standard value: 2.7 - 3.4 Ω (A/T fluid temperature 20°C) If not within the standard value, replace the solenoid valve. If within the standard value, check the harness wire between A/T control solenoid valve assembly connector and each solenoid valve connector. If a problem is not found at the steps above, check the solenoid valve O-rings and replace if necessary. (Refer to GROUP 23B,C Automatic Transmission Overhaul.)
