1. Slipping.
2. Overheating.
3. Contaminated Transmission Fluid.
4. Shuddering.
5. Increased Stall Speed.
6. Unusual Sounds.

What causes a TCC solenoid to go bad?

Any time a transmission overheats, some internal damage occurs. These situations normally end with complete transmission failure. TCC Diagnostic Trouble Codes (DTC) A faulty torque converter clutch solenoid normally sets a Diagnostic Trouble Code (DTC), which causes the Check Engine Light to come on.

Where is the automatic transmission control solenoid located?

The transmission solenoids are usually located within the valve body, the transmission control unit, or the transmission control module. The transmission control unit is a device that controls the automatic transmission, and can use sensors to calculate the inner workings of each electrical part in your vehicle.

How do you test a TCC solenoid?

The best way to test the TCC solenoid is to measure the OHMs and make sure its within a suitable range. If it is not, then simply replace it.

How do you test a TCC solenoid with a multimeter?

Go to: TEST 4: Applying 12 V To The TCC Lock-Up Solenoid….Place your multimeter in Ohms mode.

1. Place your multimeter in Ohms mode.
2. Unplug the lock up solenoid assembly from its electrical connector.
3. Measure the resistance between terminal labeled with the #1, in the image viewer above, and the solenoid assembly’s body.

How do you bypass a TCC solenoid?

To bypass the shift and TCC solenoids, you simply need to connect standard 194 light bulbs to these individual circuits coming from the PCM and then connect the other side of the bulbs to ignition B+. The light bulbs will then serve as a “load” which will simulate the solenoids.
