Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during electrical work.
Raise the vehicle using jack stands for better access.

2. Check Transmission Fluid

Remove the transmission dipstick (if equipped) and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the manufacturer-recommended transmission fluid until the correct level is achieved.
Inspect the fluid color; if it is dark or burnt, a fluid change may be necessary.

3. Inspect and Replace Engine Mounts (if applicable)

Visually check engine mounts for cracks or deterioration.
If damaged, remove the old engine mount using a socket set.
Install the new engine mount and torque it to the manufacturer's specifications.

4. Test and Replace Throttle Position Sensor (if necessary)

Disconnect the electrical connector from the throttle position sensor.
Use a multimeter to check the sensor's output voltage.
If out of spec, replace the throttle position sensor.
Reconnect the electrical connector and clear any error codes.

5. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the engine and allow it to reach normal operating temperature.
Test drive the vehicle, focusing on the shifting behavior.
