Solution

1. Preparation

Gather tools including a socket set, OBD-II scanner, and fluid catch pan.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery before working on electrical systems.

2. Check Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Reinsert the dipstick fully and remove it again to check the fluid level.
3. If low, add the appropriate type of transmission fluid (refer to the owner's manual for specifications).
4. If the fluid is discolored or burnt, proceed to a fluid change.

3. Fluid Change

Sub-steps:
1. Drain the old transmission fluid by removing the drain plug and allowing it to empty into a pan.
2. Replace the transmission filter if applicable; remove the old filter and install the new one.
3. Reinstall the drain plug and torque to manufacturer specifications (typically around 20 Nm).
4. Fill the transmission with new fluid through the dipstick tube, using a funnel, until it reaches the correct level.

4. Inspect and Replace Transmission Mounts (if necessary)

Sub-steps:
1. Locate the transmission mounts and inspect for cracks or wear.
2. If damaged, use a socket set to remove the mounting bolts.
3. Replace with new mounts, ensuring they are properly aligned.
4. Torque the bolts to the specified value (usually around 50 Nm).
