Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is on a flat surface and properly secured with jack stands if lifted.
Disconnect the battery to prevent electrical issues.

2. Inspect and Change Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check fluid level and condition.
2. If necessary, drain the old transmission fluid using a fluid pump or by removing the drain plug.
3. Replace with new transmission fluid as specified in the owner’s manual (typically Toyota ATF WS).
4. Reinsert the drain plug and torque it to manufacturer specifications (usually around 30-40 lb-ft).

3. Inspect Torque Converter and Components

Sub-steps:
1. Remove the transmission inspection cover (if applicable).
2. Check the torque converter for play or damage.
3. If the converter is faulty, remove it using a suitable socket and ratchet, and replace it with a new one.

4. Replace Transmission Mounts

Sub-steps:
1. Locate the transmission mounts and inspect for any cracks or signs of wear.
2. If damaged, support the transmission using a jack.
3. Remove the bolts securing the old mount using a socket set.
4. Install the new transmission mounts and torque the bolts to the specified torque (usually around 50-60 lb-ft).

5. Reassemble and Test

Sub-steps:
1. Reinstall any covers or components that were removed during the process.
2. Reconnect the battery.
3. Start the vehicle and check for any leaks or abnormal noises.
4. Test drive the vehicle to ensure the whirring noise has been resolved.
