Solution

1. Preparation

• Gather tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool before working on the vehicle.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
• Remove the transmission pan bolts using a socket wrench.
• Carefully lower the pan and drain the old transmission fluid into a suitable container.
• Inspect the transmission filter and replace it if necessary.
• Reinstall the pan using a new gasket, tightening the bolts to the manufacturer's specified torque.
• Refill the transmission with the recommended fluid type through the dipstick tube using a funnel.

3. Inspect and Replace Throttle Position Sensor (if faulty)

• Tools Required: Socket set, multimeter.
• Locate the throttle position sensor on the throttle body.
• Disconnect the electrical connector and remove the mounting screws.
• Test the sensor's output using a multimeter to ensure it is within specifications.
• If faulty, install a new throttle position sensor and reconnect the electrical connector.

4. Check and Replace Transmission Control Module (if necessary)

• Tools Required: OBD-II scanner, socket set.
• Locate the TCM within the vehicle (typically near the transmission).
• Disconnect the electrical connectors from the TCM.
• Remove the module using a socket set.
• Reinstall a new TCM if the diagnostic steps indicated a failure.
