TRANSMISSION

1993 Toyota Corolla • 4 cylinder 2WD Automatic • 153,000 miles

1993 Toyota Corolla transmission has and engine trouble code of 63 no.2 solenoid valve and code 64 SL solenoid valve code. How can I fixes theses codes.

Both are transmission trouble codes and diagnostic procedures are as follows.

CODE NO. 63 (NO. 2 SOLENOID)

1. Access ECT ECU. See Fig. 1 & Fig. 2. Using ohmmeter, check resistance between terminal S2 and body ground with connector removed from ECT ECU. See Fig. 22.

2. Resistance should be 11-15 ohms. If resistance is okay, replace ECT ECU. If resistance is not within specification, remove oil pan. Disconnect electrical connector (Pink/Green wire on Paseo, Black wire on all others) at No. 2 solenoid.

3. Check resistance between electrical terminal on No. 2 solenoid and body ground. Replace No. 2 solenoid if resistance is not 11-15 ohms. If resistance is 11-15 ohms, inspect and repair wiring between No. 2 solenoid and ECT ECU.

CODE NO. 64 (LOCK-UP SOLENOID)
NOTE: Lock-up solenoid terminal SL, may also be known as solenoid No. 3 (SOL 3) terminal.

1. Access ECT ECU. See Fig. 1 & Fig. 2. Using ohmmeter, check resistance between terminal SL and body ground with connector removed from ECT ECU. See Fig. 27.

2. Resistance should be 11-15 ohms. If resistance is okay, replace ECT ECU. If resistance is not within specification, disconnect electrical connector at lock-up solenoid.

3. Check resistance between electrical terminal on lock-up solenoid and body ground. Replace lock-up solenoid if resistance is not 11-15 ohms. If resistance is 11-15 ohms, inspect and repair wiring between lock-up solenoid and ECT ECU.

Could you provide detailed instructions on how to access the no.2 and SL solenoid.

To access the solenoids, you would have to remove the valve body which means dropping the oil pan.

Check the solenoids connectors at transmission case for contaminations and poor contact first. Water tends to collect at the connectors resulting in poor contact.

SHIFT SOLENOIDS R & I
Removal & Installation
Solenoids are located on the valve body. Remove bolt, solenoid and "O" ring from valve body. To install, reverse removal procedure using NEW "O" ring.
