Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, socket set, torque wrench, fluid catch pan, and transmission fluid.
Ensure the vehicle is parked on a level surface, and the engine is turned off.

2. Inspect and Refill Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the fluid level.
3. If low, add the recommended Toyota transmission fluid (typically ATF WS) through the dipstick tube.
4. Check the fluid condition; it should be a bright red color. If dark or burnt, a fluid change is needed.

3. Address Leaks

Sub-steps:
1. Inspect the transmission pan and gasket for signs of wear or damage.
2. Tighten any loose bolts (use torque specifications from the service manual).
3. Replace the gasket if leaking, ensuring to clean the mating surfaces before installation.

4. Replace Transmission Fluid (if necessary)

Sub-steps:
1. Place the fluid catch pan under the transmission pan.
2. Remove the transmission pan bolts and carefully lower the pan.
3. Replace the transmission filter if applicable.
4. Reinstall the pan with a new gasket and torque the bolts to the specified value.

5. Test Drive

Sub-steps:
1. Start the engine and allow it to warm up.
2. Shift through all gears while parked to circulate the fluid.
3. Test drive the vehicle to confirm the whining noise has ceased.
