why does my Honda Pilot YF3 (2016-2022) transmission make a whining noise

Solution

1. Preparation

• Park the vehicle on a level surface and set the parking brake.
• Gather tools: OBD-II scanner, socket set, fluid pump, funnel, and a fluid catch pan.

2. Check and Replace Transmission Fluid

• Inspect Fluid Level:

  • Remove the transmission dipstick and wipe it clean.
  • Reinsert, then remove again to check the fluid level; add fluid if low.

• Change Fluid:

  • Place a fluid catch pan under the transmission pan.
  • Remove the transmission pan bolts using a socket set.
  • Lower the pan carefully and drain the old fluid.
  • Replace the transmission filter if applicable.
  • Clean the pan and magnet, then reinstall with a new gasket.
  • Refill with the appropriate transmission fluid (consult owner’s manual for specifications).

3. Inspect Transmission Components

• Visual Inspection:

  • Check for wear on gears and bearings by removing the transmission cover if accessible.
  • Look for signs of damage to the torque converter.

• Torque Converter Check:

  • If noise persists, consider checking or replacing the torque converter as it can cause whining noises.

4. Test Drive

• After repairs, perform a test drive under various conditions to ensure that the whining noise has been resolved.
