Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Locate the engine mounts by consulting the vehicle service manual.
2. Use a socket set to remove the bolts securing the engine mounts to the engine block and chassis.
3. Carefully lift the engine slightly using a jack with a wooden block to relieve stress on the mounts.
4. Remove the old engine mounts and install new ones, ensuring they are aligned correctly.
5. Torque the mounting bolts to the manufacturer's specifications (typically around 30-50 Nm, but refer to the service manual for exact values).

3. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fluid access point.
2. Remove the dipstick and check the transmission fluid level; add fluid if low.
3. If the fluid appears dirty or smells burnt, proceed to replace it.
4. Drain the old transmission fluid using a fluid pump or by removing the drain plug.
5. Replace the transmission filter if applicable and refill with the recommended transmission fluid (consult the owner's manual for specifications).

4. Final Assembly and Cleanup

Sub-steps:
1. Reconnect the battery once all repairs are completed.
2. Start the engine and check for any unusual noises or vibrations.
3. Inspect for leaks around the engine mounts and transmission.
4. Lower the vehicle and ensure all tools are removed from the engine bay.
