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.
