Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, fluid pump, funnel, and safety gloves.
Park the vehicle on a level surface and engage the parking brake.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick (if applicable) or drain plug.
Remove the dipstick (or drain plug) to check fluid level.
- If low, add the recommended transmission fluid (check owner's manual for specifications).
Inspect fluid condition:
- If the fluid is dark or has a burnt smell, proceed to replace it.
Drain old fluid (if replacing):
- Place a drain pan under the transmission, remove the drain plug, and allow fluid to fully drain.
Replace the transmission filter (if applicable):
- Remove the transmission pan and replace the filter according to manufacturer specifications.
Refill with new transmission fluid:
- Use a fluid pump to add new fluid through the dipstick tube or fill port until it reaches the correct level.

3. Inspect and Repair Transmission Control Module (TCM)

Disconnect the battery to avoid electrical shorts.
Remove the TCM from its housing.
Inspect the TCM for visible damage, burnt circuits, or connector issues.
Replace TCM if damaged:
- Connect the new TCM and securely mount it back in place.
Reconnect the battery and clear any error codes using the OBD-II scanner.

4. Adjust Gear Linkage (if necessary)

Inspect the gear linkage for proper alignment and connection.
Loosen the adjustment bolts on the linkage.
Align the linkage according to manufacturer specifications.
Tighten the adjustment bolts to the recommended torque value.
