Shift solenoid replacement instructions

This is not a mechanical issue so you may not see anything wrong with the way it drives but it is an issue with the shift solenoid circuit or the solenoid itself. So as soon as you drive it sees the issue and turns the light on.

I attached all the testing that we need to do in order to confirm what this issue is.

Here is a guide that talks about the different types of transmission issues:

Lets run through this material and see what we find. Thanks

There's no way for you to test the converter. That's what the computer is programmed to do for you.

The shift solenoids are mounted on the side of the transmission and I believe they may all be packaged together as one part.

This code is a lockup solenoid malfunction, also called the TCC. After car has shifted into high, at a designated speed, the lockup solenoid will engage, reducing RPM and saving gas. In your case it sounds like the lockup solenoid is not disengaging, causing the engine to stall, run rough. It is sort of like starting in second gear (on manual trans) from a start. You can try changing fluid again, but the final fix will be to replace solenoid. Shop around for a better price, but a malfunctioning solenoid will not fix itself.

Hello,

You will need to drop the pan which this guide will give you an idea on.

Here is the wiring diagrams so you can see its the solenoid with the yellow wire is the one you want to replace.

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

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.

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.

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.
