2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check fluid level and condition (should be bright red and clean).

3. Replace the transmission filter if applicable (remove the transmission pan, clean surfaces, and install a new filter).
4. Refill the transmission with the recommended fluid (Toyota ATF WS) through the dipstick tube until the proper level is reached.

3. Inspect Transmission Mount

Sub-steps:
1. Locate the transmission mount and visually inspect for cracks or excessive wear.
2. If damaged, remove the bolts securing the mount.
3. Replace with a new mount and tighten bolts to the manufacturer's specified torque.

4. Check for Internal Issues

Sub-steps:
1. If the whining persists, it may indicate internal component wear. Consult a professional for a complete transmission inspection.
2. Consider a transmission rebuild or replacement if necessary based on professional assessment.
