Solution

1. Preparation

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

2. Change Transmission Fluid

Drain the Fluid
- Remove the transmission pan bolts using a socket set.
- Allow the old fluid to drain completely into a suitable container.
Replace the Filter
- Remove the old transmission filter and replace it with a new filter, ensuring it is seated correctly.
Install the Pan
- Clean the pan and apply a new gasket.
- Reinstall the pan and torque bolts to the manufacturer's specifications (typically around 10-15 ft-lbs).

3. Inspect and Replace Torque Converter (if necessary)

Remove Torque Converter
- Disconnect the transmission from the engine, ensuring to support the transmission with a jack.
- Unbolt the torque converter from the flexplate using a socket set.
Inspect the Converter
- Check for signs of wear or damage; replace if necessary.
Install New Torque Converter
- Align the new torque converter with the transmission and flexplate.
- Bolt it in place and ensure it is securely fastened.

4. Refill Transmission Fluid

Refill the transmission with new fluid through the dipstick tube, using the recommended type for the Ford Explorer (typically Mercon LV or equivalent).

5. Final Checks

Reconnect the battery.
Start the engine and allow it to reach operating temperature.
Check for leaks and ensure proper fluid levels are maintained.
