Solution

1. Preparation

Tools Required: Wrench set, funnel, fluid catch pan, jack and jack stands, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the engine to cool before starting any work.
Lift the vehicle using a jack and secure it with jack stands.

2. Drain Old Transmission Fluid

Locate the transmission fluid drain plug, typically found on the bottom of the transmission pan.
Place the fluid catch pan under the drain plug.
Use the appropriate wrench to remove the drain plug and allow the old fluid to completely drain into the pan.
Inspect the drain plug for metal shavings or debris, which could indicate internal wear.

3. Replace Transmission Filter (if applicable)

If your model has a transmission filter, locate it and remove the old filter.
Clean the filter housing and install the new filter ensuring it is securely in place.

4. Reinstall Drain Plug

Reinstall the drain plug and tighten it to the manufacturer’s specified torque (typically around 30 ft-lbs).
Clean any residual fluid from the area around the drain plug.

5. Add New Transmission Fluid

Locate the transmission fluid fill plug, usually found on the side of the transmission.
Remove the fill plug and use a funnel to add new transmission fluid. Refer to the owner's manual for the correct type and amount of fluid (typically Honda ATF DW-1).
Start the engine and allow it to reach operating temperature while checking for leaks around the drain and fill plugs.

6. Check Fluid Level

With the vehicle still running and in the park position, check the transmission fluid level using the dipstick (if equipped).
Add fluid as necessary until it reaches the appropriate level on the dipstick.
