Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety.
Raise the front of the vehicle using a jack and secure with jack stands.

2. Check Transmission Fluid

Remove the transmission dipstick.
Wipe clean, reinsert, and check fluid level; add fluid if low, ensuring it meets the Ford specification.

3. Inspect Torque Converter Clutch Solenoid

Locate the torque converter clutch solenoid on the transmission.
Disconnect the electrical connector.
Using a multimeter, check the resistance of the solenoid; compare with manufacturer specifications. If out of range, replace the solenoid.

4. Replace Torque Converter (if necessary)

Drain the transmission fluid using a pan.
Remove the transmission pan and filter to access the torque converter.
Unbolt the torque converter from the flex plate and slide it out.
Install the new torque converter, making sure it is fully seated.
Reinstall the transmission pan with a new gasket and refill with the appropriate transmission fluid.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Start the engine and allow it to reach operating temperature.
Check for leaks and monitor the operation of the torque converter.
