Shift Solenoid: Testing and Inspection

2. INSPECT SOLENOID
a. Disconnect the connector from the ECT computer.
b. Measure the resistance between S(1), S(2), S(L) and ground.

Resistance: 11 - 15 ohm

c. Apply battery voltage to the solenoid. Check that an operation noise can be heard from the solenoid.

NOTE: If there is foreign matter in the solenoid valve, there will be no fluid control even with solenoid operation.




3. CHECK SOLENOID SEALS
If there is foreign material in the solenoid valve, there will be no fluid control even with solenoid operation.

a. Check No.1 and No.2 solenoid valves.
- Applying 5 kg/Sq. cm (71 psi, 490 kPa) or compressed air, check that the solenoid valves do not leak the air.
- When supply battery voltage to the solenoids, check that the solenoid valves open.




b. Check the lock-up solenoid valve.
- Applying 5 kg/Sq. cm (71 psi, 490 kPa) of compressed air, check that the solenoid valve opens.
- When supply battery voltage to the solenoid, check that the solenoid valve does not leak the air.
