Solution

1. Preparation

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

2. Check and Change Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check fluid level.
2. If low, use a fluid pump to add the correct type of transmission fluid (refer to owner's manual for specifications).
3. If the fluid is dirty or contaminated, drain the old fluid by removing the transmission pan bolts and lower the pan carefully.
4. Clean the transmission pan and replace the filter if applicable.
5. Reinstall the pan, torque bolts to manufacturer specifications, and refill with new fluid.

3. Reprogram or Replace TCM

Sub-steps:
1. Disconnect the battery to ensure safety before working with electrical components.
2. Locate the TCM (usually found near the transmission).
3. Check for any visible damage or corrosion on connectors.
4. If necessary, replace the TCM with a new unit and ensure proper connections.
5. Reconnect the battery and use the OBD-II scanner to reprogram TCM settings if required.

4. Inspect and Replace Engine Mounts

Sub-steps:
1. Visually inspect the engine mounts for cracks or excessive wear.
2. If damaged, support the engine with a jack and remove the old mounts.
3. Install new mounts, ensuring they are aligned properly.
4. Torque the mount bolts to the specified values.
