Power Steering Fluid:
1. Locate the power steering reservoir.
2. Check the fluid level against the markings on the reservoir.
3. If low, add the specified Honda power steering fluid.

3. Check and Replace Accessory Belts

Inspect the accessory belts for cracks, fraying, or signs of wear.
If damaged, loosen the tensioner and remove the worn belt.
Install a new belt according to the vehicle’s specifications, ensuring proper tension.

4. Address Transmission Issues

If whining persists after fluid inspection, consider checking the transmission for internal damage.
Consult a professional technician for a thorough diagnosis of the transmission.
If repairs are needed, follow manufacturer guidelines for disassembly, inspection, and replacement parts.
