Sub-steps:
1. Remove the transmission fluid dipstick and check the fluid level.
2. If fluid is low, add the recommended type of transmission fluid (consult owner’s manual for specifications).
3. If fluid is dark or smells burnt, drain the old fluid using a fluid pump.
4. Replace with new transmission fluid, ensuring the correct type and quantity is used.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan using a socket set.
2. Take out the old filter, noting any seals or gaskets.
3. Install the new transmission filter, ensuring it is seated properly.
4. Replace the transmission pan with a new gasket, torqueing the bolts to manufacturer specifications.

4. Test Transmission Solenoids

Sub-steps:
1. Disconnect the electrical connector from each solenoid.
2. Use a multimeter to check for resistance (refer to service manual for specific values).
3. Replace any faulty solenoids, ensuring proper fit and connection.

5. Reprogram Transmission Control Module (if necessary)

Sub-steps:
1. Connect the OBD-II scanner to the vehicle.
2. Follow instructions on the scanner to access the TCM.
3. Check for software updates and apply them if available.
