Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, and shop towels.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Change Transmission Fluid

Remove the transmission fluid dipstick or access the transmission fill plug.
Using a funnel, add the recommended type of transmission fluid (consult the owner's manual for specifications).
If the fluid is dirty or burnt, drain the old fluid by removing the drain plug.
Replace the drain plug and refill with fresh transmission fluid to the proper level.

3. Inspect and Repair Gear Linkage

Visually inspect the gear linkage for any signs of wear or damage.
If damaged, remove the linkage components using a socket set.
Replace any worn or broken parts with new components.
Reassemble the gear linkage and ensure it is properly aligned.

4. Test Transmission Control Module

Disconnect the battery to ensure safety.
Remove the transmission control module from its housing.
Test the module using a multimeter to check for any faults.
If faulty, replace the module with a new one and reconnect all wiring.

5. Check Clutch or Torque Converter (if applicable)

For manual transmissions, check the clutch for wear. If it is worn, it may need replacement.
For automatic transmissions, ensure the torque converter is functioning correctly.
If necessary, remove the transmission to access and replace the torque converter.
