Solution

1. Preparation

Gather tools and parts.
Disconnect the vehicle battery to avoid electrical issues.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Check Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If low, add the manufacturer-recommended transmission fluid until the proper level is reached.
Inspect the fluid for burnt smell or dark coloration, indicating contamination.

3. Fluid Change (if necessary)

Drain the old transmission fluid using a fluid suction pump or by removing the drain plug.
Replace the transmission filter if applicable.
Refill with the manufacturer-specified transmission fluid, ensuring the correct amount is added.

4. Inspect and Replace Components

If error codes indicate issues with the TCM or solenoids, remove the transmission pan to access these components.
Replace any faulty solenoids or the TCM as needed, following manufacturer specifications for installation.

5. Test Drive and Recheck

Reconnect the battery and start the vehicle, allowing the transmission fluid to circulate.
Conduct a test drive to confirm that the transmission is functioning properly.
Recheck the fluid level and leak status after the test drive.
