Remove the drain bolt with a 3/8 ratchet. Allow the transmission fluid to drain fully. Replace the washer on the drain bolt and wipe it clean before installation.
Reinstall the drain bolt and tighten it to 35 ft-lb.
Remove the 17mm bolt on the side of the transmission housing. This is where you will check the transmission fluid level if your Honda does not have a dipstick. The level is full when transmission fluid starts to drip out of this hole.
Remove the fill plug located at the top of the automatic transmission housing. This is a black plug with a hook at the end.
Add the recommended Honda automatic transmission fluid until it starts to drip at the check hole.
Remove the funnel and reinstall the cap for the filler hole. Install the 17mm bolt on the side of the transmission housing.
Start the engine, check for any issues/leaks, and drive it for 15 minutes to bring it to normal operating temperature.
Recheck the automatic transmission fluid level via the check hole. There should be a small amount of automatic transmission fluid dripping from the hole when removing the 17mm bolt. If there is no transmission fluid dripping from the check hole, top off until you see transmission fluid dripping from the check hole.
- Drain bolt: 35 ft-lb.
- When you drain the transmission pan and refill, you only change about 40% of the transmission fluid.
- Check transmission fluid level at operating temperature with the engine off—car on level ground.
