Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts during the repair.

2. Fluid Change and Filter Replacement

Drain Transmission Fluid
- Place a drain pan under the transmission pan.
- Remove the transmission drain plug (if equipped) or the pan bolts to drain the fluid completely.
- Dispose of old fluid properly.
Remove Transmission Pan
- Unscrew all bolts securing the transmission pan.
- Carefully lower the pan and inspect for metal shavings or debris inside.
Replace Filter
- Remove the old transmission filter, ensuring all old gaskets are removed.
- Install the new transmission filter, ensuring it is seated properly.
Clean Transmission Pan
- Clean the transmission pan thoroughly with a solvent to remove old gasket material.
Install New Gasket and Pan
- Place a new gasket on the transmission pan.
- Reinstall the pan, tightening the bolts to the manufacturer's torque specifications (usually around 8-10 ft-lbs).
Refill Transmission Fluid
- Refill the transmission with the correct type and amount of fluid as specified in the owner's manual (usually Honda ATF DW-1).
- Start the engine and let it run for a few minutes while checking for leaks.

3. Inspect and Replace Transmission Mounts (if necessary)

Check Transmission Mounts
- Visually inspect the mounts for cracks or excessive wear.
- Use a jack to support the transmission slightly while you inspect the mounts.
Replace Mounts
- If mounts are damaged, remove the bolts securing them to the transmission and the chassis.
- Install the new mounts and torque the bolts to the specified values.
