why does my Ford F-150 Fourteenth Generation (2021-present) transmission hesitate when shifting

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the vehicle battery to prevent electrical shorts.
• Ensure the vehicle is parked on a level surface and use wheel chocks for safety.

2. Transmission Fluid and Filter Change

1. Drain Transmission Fluid

   • Remove the transmission pan bolts using a socket set.
   • Carefully lower the pan to drain the fluid into a suitable container.
   • Clean the pan and magnet of any metal shavings.

2. Replace Transmission Filter

   • Remove the old transmission filter and discard it.
   • Install the new transmission filter, ensuring it is seated properly.

3. Reinstall Transmission Pan

   • Apply a new gasket to the transmission pan.
   • Reinstall the pan and torque the bolts to the manufacturer’s specifications (typically around 10-12 ft-lbs).

3. Check Electrical Connections

1. Inspect TCM Wiring

   • Examine the wiring harness connected to the TCM for any signs of damage or corrosion.
   • Clean any corroded connections with an electrical contact cleaner.

2. Reconnect TCM and Battery

   • Reconnect the TCM and then reconnect the vehicle battery.

4. Test Drive

• Take the vehicle for a test drive to check for proper shifting behavior and any remaining issues.
