Solution

1. Preparation

Gather tools and materials: OBD-II scanner, transmission fluid, funnel, rags, socket set, and torque wrench.
Ensure the vehicle is on a level surface and the engine is off.
Allow the vehicle to cool down if it has been running.

2. Check and Refill Transmission Fluid

Locate the transmission dipstick under the hood.
Remove the dipstick and wipe it clean with a rag.
Reinsert the dipstick fully and remove it again to check the fluid level.
If low, use a funnel to add the appropriate type of transmission fluid (refer to the owner's manual for specifications).
Start the engine and let it run for a few minutes, then recheck the fluid level, adding more if necessary.

3. Inspect Transmission Components

Conduct a visual inspection of the transmission linkage and cables.
Look for any signs of fraying, disconnection, or damage.
If any issues are found, replace the damaged components.

4. Test Transmission Control Module

Connect an OBD-II scanner to the vehicle's diagnostic port.
Retrieve any transmission-related error codes.
If the TCM shows faults, consider reprogramming or replacing it as needed.

5. Repair or Replace Transmission Seals

If fluid leaks are present, identify the source of the leak.
Remove any components blocking access to the leaking seals.
Replace the faulty seals and reassemble components, ensuring proper torque specifications.
