Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather tools and materials: OBD-II scanner, socket set, transmission fluid, funnel, torque wrench.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick, then remove it again to check the fluid level.
If low, add the recommended transmission fluid to the correct level. Ensure the fluid is in good condition (not burnt or contaminated).

3. Inspect Transmission and Engine Mounts

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect the transmission mounts for cracks or excessive wear.
If damaged, replace with new mounts, ensuring to use the correct torque specifications when re-installing.

4. Test Throttle Position Sensor

Disconnect the electrical connector from the throttle position sensor.
Use a multimeter to test for voltage output as you manually move the throttle. Verify it matches the manufacturer's specifications.
If faulty, replace the throttle position sensor.

5. Verify Battery and Alternator Function

Use a multimeter to check the battery voltage (should be around 12.6 volts when off and 13.7-14.7 volts when running).
If readings are outside this range, consider replacing the battery or alternator.
