Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Transmission Fluid

Tools Required: Wrench set, transmission fluid pump, funnel, OBD-II scanner.
Remove the transmission fluid pan using a socket set, allowing old fluid to drain into a suitable container.
Inspect the pan for metal shavings or debris; clean as necessary.
Replace the transmission filter if applicable.
Refill the transmission with the manufacturer-recommended fluid type (consult owner's manual for specifications).
Reattach the fluid pan and torque bolts to the specified value (typically around 10-15 ft-lbs).

3. Replace Throttle Position Sensor (if faulty)

Tools Required: Screwdriver set, multimeter.
Disconnect the electrical connector from the throttle position sensor.
Remove the sensor from the throttle body using a screwdriver.
Install the new throttle position sensor and reconnect the electrical connector.
Clear any stored error codes using the OBD-II scanner.

4. Check and Replace Motor/Transmission Mounts (if damaged)

Tools Required: Jack and jack stands, socket set.
Lift the vehicle using a jack and secure it with jack stands.
Inspect motor and transmission mounts for cracks or excessive wear.
Remove the old mounts using a socket set.
Install new mounts and ensure they are securely fastened.
