Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Raise the vehicle securely on jack stands if necessary.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back into the tube and remove it again to check fluid level.
If low, add the recommended transmission fluid (typically Mercon LV for Ford).

3. Inspect and Repair Leaks

Locate any visible leaks around the transmission pan, seals, and hoses.
If any seals or gaskets are damaged, replace them using the appropriate sealant.
Tighten any loose bolts on the transmission pan to stop leaks.

4. Repair Gear Shift Linkage

Inspect the gear shift linkage for any signs of wear or damage.
If adjustment is needed, locate the adjustment points on the linkage and ensure they are properly aligned.
Replace any worn components if necessary.

5. Test the Transmission Control Module

Use a multimeter to check the voltage at the transmission control module connectors.
If the module is faulty, remove it and replace it with a new one, following the manufacturer's specifications for installation.

6. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and check for any error codes again.
Test drive the vehicle to ensure smooth shifting and operation.
