Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid dipstick, funnel, multimeter.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery before performing any electrical checks.

2. Transmission Fluid Inspection

Remove the transmission fluid dipstick and wipe it clean.
Insert it back into the tube and remove it again to check the fluid level.
If low, add the recommended transmission fluid type (e.g., Mercon LV for Ford).
If the fluid is dark or smells burnt, a fluid change is necessary.

3. Transmission Linkage Adjustment

Inspect the transmission linkage for any signs of wear or misalignment.
If misaligned, adjust the linkage according to the service manual specifications.
Tighten any loose bolts or fasteners connected to the transmission.

4. Torque Converter Inspection

If the jerking persists, inspect the torque converter for proper operation.
Remove the transmission pan (if necessary) to access the torque converter.
Check for signs of wear or damage; replace the torque converter if needed.
