Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace TCC Solenoid

Tools Required:
- Socket set
- Torque wrench
- Multimeter
- Transmission fluid
Sub-steps:
1. Remove the transmission pan by loosening the bolts and draining the fluid into a container.
2. Once the pan is removed, locate the TCC solenoid.
3. Disconnect the electrical connector from the solenoid.
4. Remove the solenoid from its mounting location.
5. Install the new TCC solenoid by reversing the removal steps. Ensure it is seated properly.
6. Reinstall the transmission pan with a new gasket and torque the bolts to the manufacturer’s specifications.
7. Refill the transmission with the recommended fluid type.

3. Electrical Inspection and Repair

Tools Required:
- Multimeter
- Wiring harness repair kit
Sub-steps:
1. Inspect the wiring harness for any signs of fraying, corrosion, or disconnection.
2. Use a multimeter to check the continuity of the wiring between the TCC solenoid and the PCM (Powertrain Control Module).
3. Repair or replace any damaged wires or connectors as necessary.

4. Reconnect Battery and Test

Reconnect the battery.
Clear the error code using the OBD-II scanner.
Start the vehicle and allow it to reach operating temperature.
