P1753: Problem in Torque Converter Clutch Solenoid Valve Circuit

May need to test/replace solenoids. Back probed the solenoid connector at yellow wire and see if it's getting power when lock up is supposed to come on.

If so, most likely a faulty torque converter. The other possibility is a missing or damaged o-ring from the snout of the torque converter, this usually throws a different code though.

Hope this helps.

Sounds definitely like faulty solenoid to me as well. Doesn't sound like you need removal instructions as you seem to know queit a bit about this, but if you do need some guidance just let me know.

Generally, if you unplug the TCC solenoid at the transmission and the symptoms go away, you have found the problem. But sometimes this can be misleading because you don't know for sure if it's a bad solenoid, dirt in the valve body or a bad signal from the ECM. Follow test methods below for proper testing of the solenoid.

TEST #1
Check For 12 Volts To Terminal A At Transmission

Raise the vehicle on the lift so the driving wheels are off the ground.
Connect the alligator clip of your test light to ground. Unplug the wires at the case and place the tip of your test light on the terminal marked A.
Do not depress the brake pedal.
Computer controlled vehicles: turn on the ignition and the tester should light.
All other vehicles: start the engine and bring to normal operating temperature.
Raise RPM to 1500 and the tester should light. If tester lights continue with Regular Method.
If the tester does not light go to Test # 2.

TEST #2
Check For 12 Volts To Terminal A At The ALDL

Note: ALDL quick methods, when given, are a way to perform many of the tests at the Assembly Line Diagnostic Link (ALDL). This will allow you to do most of the electrical checks from the driver's seat and save much valuable diagnostic time.
Connect one end of a test light to terminal A at the ALDL.
Connect the other end to terminal F at the ALDL.
Turn on the ignition and the tester should light. Note: some transmissions, like the 125C must shift to 3rd before the tester will light.
If the tester lights, you have 12 volts to terminal A at the transmission. Go to Test # 6.
If the tester does not light, then check for 12 volts by the regular method.

I believe by performing one of these tests, you will find your TCC solenoid is faulty. However, if these tests come out OK then let me know and I will post further tests.

Hope this helps.
