Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, fluid pump, transmission fluid, rags.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery if working on electrical components.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick or fill plug.
Remove the dipstick or fill plug and check fluid level.
If low, use a fluid pump to add the correct type of transmission fluid as specified in the owner’s manual.
Inspect the fluid condition; if it is dark or has a burnt smell, perform a full fluid change.
To change the fluid, drain the old fluid by removing the transmission pan (if applicable) and replace the filter if needed.
Refill the transmission with new fluid to the proper level and check for leaks.

3. Inspect and Replace Transmission Mounts (if necessary)

Visually inspect transmission mounts for cracks or wear.
If damaged, support the transmission with a jack and remove the bolts securing the mounts.
Replace with new mounts and torque bolts to manufacturer specifications.
Lower the transmission and verify that it sits securely in place.

4. Test or Replace Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Use a multimeter to check the sensor's output voltage against specifications.
If faulty, disconnect the wiring harness and remove the sensor.
Install a new throttle position sensor and reconnect the wiring harness.
