how to fix Ford Explorer transmission problems when shifting

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is securely lifted and supported with jack stands.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Fluid Change

• Tools Required: Fluid pump, transmission fluid (as specified by manufacturer), drain pan, socket set.
• Remove the transmission pan bolts and carefully lower the pan to drain the old fluid.
• Inspect the pan for debris and clean it thoroughly before reinstallation.
• Replace the transmission filter if equipped; ensure the new filter is correctly seated.
• Refill the transmission with the recommended fluid through the dipstick tube using a fluid pump, checking the level frequently.

3. Electrical Inspection

• Tools Required: Multimeter, wiring diagrams.
• Inspect the wiring harness for the transmission control module for fraying or corrosion.
• Check the connector pins for proper connectivity and clean if necessary.
• Test the transmission control module with a multimeter to verify voltage and ground signals.

4. Component Replacement (if necessary)

• If diagnostics indicate a faulty solenoid or valve body, proceed with replacement.
• Tools Required: Socket set, torque wrench.
• Remove the transmission pan again to access the solenoids or valve body.
• Disconnect the wiring harness from the affected solenoid or valve body and unbolt it from the transmission.
• Install the new component, torque the bolts to manufacturer specifications, and reassemble the transmission pan.
