Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on the vehicle.

2. Fluid Check and Replacement

Sub-steps:
1. Locate the transmission dipstick or fill port.
2. Remove the dipstick and wipe it clean; reinsert and check fluid level.
3. If fluid is low, or if it appears dark or has a burnt smell, prepare to change it.
4. Drain the old transmission fluid using a drain pan. Remove the drain plug if applicable.
5. Replace the drain plug, ensuring it is torqued to the manufacturer’s specifications (usually around 30 lb-ft).
6. Fill the transmission with new fluid as specified in the owner’s manual. Use Honda ATF DW-1 or equivalent.

3. Inspect and Repair Components

Sub-steps:
1. Inspect the transmission mount for cracks or excessive wear; replace if necessary.
2. Check for any loose bolts on the transmission case and tighten to manufacturer specifications.
3. If whirring persists, remove the transmission pan to inspect for metal shavings or debris.
4. Clean the pan and replace the filter if the transmission has one; reinstall the pan with a new gasket.
5. Refill the transmission with the correct fluid level as previously outlined.
