why does my Ford Explorer's transmission slip when accelerating

Solution

1. Preparation

• Gather tools and materials:
  • Tools: OBD-II scanner, socket set, fluid catch pan, funnel, torque wrench, multimeter.
  • Parts: New transmission fluid, transmission filter kit, new seals.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Allow the engine to cool if it has been running.

2. Change Transmission Fluid

1. Drain Fluid:
   • Locate the transmission pan and remove the bolts using a socket set.
   • Position a fluid catch pan under the pan and slowly remove it to let the old fluid drain completely.
2. Replace Filter:
   • Remove the old transmission filter from the valve body.
   • Install the new filter, ensuring it is seated properly.
3. Clean Pan:
   • Clean the transmission pan thoroughly to remove any debris or sludge.
   • Inspect the magnet in the pan for metal shavings and clean if necessary.
4. Reassemble:
   • Install a new gasket on the transmission pan.
   • Reattach the transmission pan and torque the bolts to manufacturer specifications (typically around 10-12 ft-lbs).
5. Refill Fluid:
   • Use a funnel to fill the transmission with the appropriate type of new fluid (check the owner’s manual for specifications).
   • Start the engine and cycle through the gears to allow the fluid to circulate.

3. Test Drive

1. Check Fluid Level:
   • After the test drive, check the transmission fluid level again and top off as needed.
2. Monitor Performance:
   • During the test drive, pay attention to shifting quality and any noises from the transmission.
