Problem Statement

Learn to diagnose and fix delayed shifting issues in Ford Explorer (2011-2019). Step-by-step guide with symptoms, diagnostic steps, and repair instructions.

Affected Component

Transmission

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before opening components.

Symptoms

•Delayed engagement when shifting from park to drive or reverse
•Hesitation during acceleration after shifting
•Harsh or rough shifting between gears
•Check engine light illuminated
•Unusual noises from the transmission during shifting
•Increased RPMs without corresponding acceleration

Diagnostic Steps

1
Scan the vehicle’s onboard computer using an OBD-II scanner to check for any transmission-related fault codes.
2
Inspect the transmission fluid level and condition; low or dirty fluid can affect shifting performance.
3
Check for any external leaks around the transmission pan and cooler lines.
4
Verify the operation of the throttle position sensor (TPS) using a multimeter to ensure it’s functioning properly.
5
Inspect the transmission control module (TCM) and wiring for any damage or corrosion.
6
Test drive the vehicle to replicate the issue and note any specific conditions that worsen the delay.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•OBD-II scanner
•Socket set
•Torque wrench
•Transmission fluid pump
•Fluid catch basin
•Multimeter
•Screwdrivers

Parts Required

•Transmission fluid (specific type as per the owner’s manual)

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Transmission Fluid Change

Tools Required: Socket set, torque wrench, transmission fluid pump, fluid catch basin.
Sub-steps:
1. Remove the transmission fluid pan by loosening the bolts with a socket set.
2. Allow the old fluid to drain completely into the catch basin.
3. Clean the transmission pan and replace the filter if applicable.
4. Reinstall the transmission pan with a new gasket, torqueing the bolts to the manufacturer’s specifications (typically around 10-12 ft-lbs).
5. Use a fluid pump to fill the transmission with the correct type and amount of new fluid (check owner’s manual for specifications).

3. Throttle Position Sensor (TPS) Inspection

Tools Required: Multimeter, screwdriver.
Sub-steps:
1. Locate the throttle position sensor on the throttle body.
2. Disconnect the electrical connector and remove the TPS using a screwdriver.
3. Test the TPS using a multimeter; ensure it produces a smooth voltage change as the throttle is opened.
4. If faulty, replace the TPS with a new one and reconnect the electrical connector.

4. Transmission Control Module (TCM) Check

Tools Required: OBD-II scanner.
Sub-steps:
1. Reconnect the battery and start the vehicle.
2. Use an OBD-II scanner to check for any current or historic codes related to the TCM.
3. If codes indicate a malfunction, consider reprogramming or replacing the TCM per manufacturer instructions.
