Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.

2. Fluid Check and Change

Fluid Level Check:
- Locate the transmission dipstick (if equipped) and remove it.
- Wipe it clean, reinsert, and check fluid level.
Fluid Change:
- Raise the vehicle using a jack and secure with jack stands.
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan to drain fluid.
- Replace the old fluid with new transmission fluid that meets Ford specifications (refer to owner's manual).
- Reattach the transmission pan and torque bolts to manufacturer specifications.

3. Inspect and Replace Components

Inspect Solenoids:
- Remove the transmission cover to access solenoids.
- Test solenoids for resistance and replace any faulty solenoids with new ones.
Inspect TCM:
- Unplug the TCM and check for corrosion or damage.
- Reconnect or replace the TCM as necessary.

4. Test Drive

Reconnect the battery and start the engine.
Take the vehicle for a test drive to ensure the jerking issue has been resolved.
