Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during the repair.
Allow the vehicle to cool down before starting work on the transmission.

2. Fluid Change

Tools Required: Socket set, fluid pump, drain pan, funnel, OBD-II scanner.
Remove the transmission pan bolts using a socket set.
Carefully lower the transmission pan to drain the old fluid into a drain pan.
Remove and replace the transmission filter, ensuring the new filter is seated properly.
Reinstall the transmission pan with a new gasket and torque bolts to the manufacturer's specifications (usually around 12-15 ft-lbs).
Fill the transmission with new fluid according to the manufacturer’s specifications (typically Mercon LV for Ford transmissions) using a funnel and fluid pump.

3. Check and Replace Transmission Range Sensor (if needed)

Tools Required: Socket set, multimeter.
Disconnect the wiring harness from the transmission range sensor.
Remove the sensor using the socket set.
Test the sensor with a multimeter to ensure it is functioning correctly; replace if faulty.
Install the new sensor and reconnect the wiring harness.

4. Test Drive

Reconnect the vehicle battery and start the engine.
Allow the engine to reach operating temperature.
Check the transmission fluid level again and top off if necessary.
Take the vehicle for a test drive to ensure the slipping issue is resolved.
