Solution

1. Preparation

Tools Required: Floor jack, jack stands, OBD-II scanner, socket set, torque wrench, transmission fluid.
Safety Warnings: Ensure the vehicle is on a level surface and secure with jack stands before working underneath.

2. Check and Change Transmission Fluid

Locate the transmission dipstick and remove it to check fluid level.
If low, add the appropriate type of transmission fluid as per the owner's manual.
If the fluid is dirty or smells burnt, proceed to change the fluid.
Remove the transmission pan using a socket set, draining the old fluid into a container.
Replace the transmission filter and clean the pan thoroughly.
Reinstall the pan with a new gasket and torque bolts to manufacturer's specifications.

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

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the mounting screws.
Replace with a new throttle position sensor and reconnect the electrical connector.
Clear any error codes from the OBD-II system and perform a throttle relearn procedure if necessary.

4. Examine and Replace Engine and Transmission Mounts (if damaged)

Inspect the mounts visually for cracks or excessive wear.
If damaged, remove the bolts securing the mounts to the engine and transmission using a socket set.
Install new mounts in reverse order and ensure they are torqued to specifications.
