1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, torque wrench, shop rags.
Ensure the vehicle is parked on a level surface and the engine is turned off. Disconnect the battery to prevent electrical shorts.

2. Fluid Change

Sub-steps:
1. Remove the transmission drain plug and allow the old fluid to drain completely into a pan.
2. Inspect the drain plug for metal shavings or debris, indicating internal damage.
3. Replace the drain plug with the specified torque (check manufacturer specifications).
4. Refill the transmission with new fluid through the dipstick tube using a funnel, ensuring the fluid type meets Ford specifications.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by unscrewing the bolts with a socket set.
2. Carefully detach the pan and clean it thoroughly, removing any sludge or debris.
3. Replace the old transmission filter with a new one, ensuring it is seated correctly.
4. Reinstall the transmission pan and secure it with the specified torque (check manufacturer specifications).

4. Reprogram TCM (if necessary)

Sub-steps:
1. Reconnect the battery and use the OBD-II scanner to access the TCM settings.
2. Follow on-screen instructions to update the TCM software if needed.
3. Clear any existing error codes.

5. Test Drive

Conduct a test drive to ensure that the jerking issue has been resolved and that shifts are smooth.
