Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, wrench set
Steps:
1. Remove the transmission dipstick and check fluid level.
2. If low or fluid is burnt, drain the transmission fluid using a fluid pump.
3. Replace with new transmission fluid (consult owner's manual for specifications).
4. Recheck fluid level after replacement and top off as needed.

3. Inspect and Replace Torque Converter Clutch Solenoid

Tools Required: Socket set, torque wrench, new TCC solenoid
Steps:
1. Remove the transmission pan to access the solenoid (drain fluid if necessary).
2. Disconnect the electrical connector from the TCC solenoid.
3. Unbolt and remove the old solenoid from its housing.
4. Install the new TCC solenoid and secure it with the specified torque.
5. Reassemble the transmission pan, ensuring proper gasket placement.

4. Adjust Transmission Control Module (if applicable)

Tools Required: OBD-II scanner
Steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to reset any transmission-related codes.
3. Perform an adaptive transmission relearn procedure if necessary (follow specific manufacturer instructions).
