Diagnosing Transmission Slipping in a 2020 Ford Explorer

Tools Required

OBD-II scanner
Transmission fluid dipstick or funnel (if applicable)
Torque wrench
Socket set
Screwdrivers
Transmission fluid (Ford Motorcraft MERCON® LV or compatible)
Fluid pump (if necessary for filling)
Multimeter (for electrical testing)
Transmission jack (if removing the transmission)

Repair Instructions

Step 1: Check and Replace Transmission Fluid

Fluid Change:
- If the fluid is low, top it off with the correct type of transmission fluid.
- If the fluid is burnt or contaminated, perform a full fluid change:
  - Remove the transmission pan using a socket set.
  - Replace the transmission filter if equipped.
  - Clean the pan and magnet (if applicable).
  - Reinstall the pan with a new gasket and torque to specification.

Step 2: Inspect and Repair Electrical Components

Wiring Inspection:
- Check the wiring harness for any signs of wear, damage, or corrosion.
- Repair or replace any damaged connectors.
Testing Sensors:
- Use a multimeter to test the transmission range sensor and speed sensors for proper voltage and resistance.
- Replace any faulty sensors as indicated by your testing.

Step 3: Scan and Address DTCs

Clear Codes:
- If any DTCs were found, clear them using the OBD-II scanner after addressing the issues.
- Test drive the vehicle to see if they reappear.

Step 4: Advanced Diagnostics (if necessary)

Transmission Control Module (TCM) Check:
- If the problem persists, the TCM may need to be reprogrammed or replaced.
- Seek a professional service for advanced diagnostics, including checking for internal transmission issues.

Conclusion

If after following the steps above the transmission slipping persists, it could indicate internal mechanical issues within the transmission itself such as worn clutches or bands. In that case, it is advisable to consult a professional transmission specialist for further diagnosis and repair. Regular maintenance, including fluid changes and inspections, can help prevent slipping issues and prolong the life of the transmission.
