Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety when working on electrical components.

2. Fluid Change

Drain Transmission Fluid
- Locate the transmission drain plug and use a socket set to remove it.
- Allow the fluid to completely drain into a suitable container.
Replace Transmission Filter
- Remove the transmission pan by unscrewing the bolts with a socket wrench.
- Take out the old filter and install a new one, ensuring it fits snugly.
Refill Transmission Fluid
- Reattach the transmission pan and torque the bolts to the manufacturer's specifications.
- Use a funnel to refill the transmission with the correct type and amount of fluid (consult your owner’s manual for specifications).

3. Inspect and Replace Components

Check Transmission Solenoids
- Remove the electrical connectors from the solenoids and test them with a multimeter.
- If any solenoid is faulty, replace it with a new one.
Inspect Transmission Mounts
- Check each mount visually and physically for cracks or wear.
- Replace any damaged mounts with new ones, ensuring proper alignment.

4. Tune-Up (if necessary)

Adjust Throttle Position Sensor
- Locate the TPS, disconnect it, and use a multimeter to ensure it is functioning correctly.
- If out of specification, adjust or replace as necessary.
