- Allow the engine to cool before working on the transmission.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the transmission pan and remove the drain plug to drain the old fluid into a pan.
3. Inspect the fluid for metal shavings or burnt odor indicating internal damage.
4. Replace the drain plug and refill the transmission with the appropriate type of fluid (refer to owner’s manual for specifications).
5. Run the vehicle and cycle through the gears to ensure proper fluid circulation.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Support the transmission with a jack and remove the bolts securing the transmission mount.
2. Remove the old mount and inspect for cracks or significant wear.
3. Install the new transmission mount and torque the bolts to the manufacturer's specifications.
4. Lower the vehicle and perform a test drive to check for improved shifting noise.

4. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
1. Remove any components obstructing access to the engine mounts (if necessary).
2. Support the engine with a jack and remove the bolts securing the engine mounts.
3. Replace with new mounts and torque bolts as per manufacturer specifications.
