Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, transmission fluid.
Ensure the vehicle is on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick or fill plug.
2. Remove the dipstick or fill plug and check the fluid level with the engine running.
3. If low, add the appropriate type of transmission fluid as specified in the owner's manual.
4. If the fluid is dark or has a burnt smell, drain and replace the fluid.
5. Torque the plug to the manufacturer's specifications before reconnecting the dipstick.

3. Check and Repair Wiring

Sub-steps:
1. Visually inspect the wiring harness leading to the transmission control module for frays or breaks.
2. Use a multimeter to check for continuity in the wiring and ensure proper voltage is reaching the TCM.
3. Repair any damaged wires and ensure all connectors are clean and secure.

4. Inspect and Replace Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids according to the service manual.
2. Remove the solenoid assembly using the appropriate socket.
3. Test the solenoids with a multimeter for resistance; replace if they are out of specification.
4. Install new solenoids and torque to the manufacturer's specifications.

5. Reconnect and Test

Sub-steps:
1. Reconnect the battery.
2. Clear the trouble codes using the OBD-II scanner.
3. Conduct a test drive to ensure that the transmission operates smoothly and the check engine light does not return.
