Fluid Recommendations
All Honda automatic transmissions use Dexron II automatic transmission fluid. This fluid directly replaces the Dexron fluid that was recommended for older models.
Checking the level
The fluid should be checked approximately once a month, and the frequency of replacement is indicated in the table at the end of the chapter. The car, before checking the fluid level, should be driven a few kilometers, allowing the oil to warm up completely, then make sure you park level and turn off the engine.
The dipstick is located on the front right side of the transmission housing, near or below the battery. It can be either a screw-in type or a small pull-out type, similar to the engine oil dipstick. To check the level, remove the dipstick, wipe it clean, and reinsert it.
The threaded dipstick does not need to be screwed in to determine the fluid level. Only the beginning of the thread should fit on the housing. By screwing the dipstick in, you will get incorrect readings.
Remove the dipstick. The fluid level should be within the dash marks, between the upper and lower markers. If fluid needs to be added, add Dexron II through the dipstick hole. Add only the amount required to keep the level within the control marks on the dipstick. Overfilling can damage the transmission. Between the upper and lower edges of the marks on the dipstick - less than 1 liter. When installing the dipstick in place, screw in the thread for the screw-in type of dipstick and tighten it only to finger tension; never use a key. Make sure the dipstick is fully seated.
Draining and filling
1. The car must be warmed up to operating temperature before starting. If possible, drive a few kilometers to warm up the box before starting to drain.
2. With the engine off, raise and support the front of the car. Agility and long arms will allow you to do this job without lifting, but it is much easier to do it with the car raised.
3. Place a tray under the box.
4. Remove the lower drain plug using a ratchet wrench inserted into the square recess; do not attempt to do this by grasping the round bolt with a pair of pliers. Drain the fluid.
5. Using a new washer, install the drain plug and tighten it to 40 Nm.
6. Fill the transmission with oil through the dipstick hole. On later models with a pull-out dipstick, you may need a narrow funnel. Check the level with the dipstick often. Do not overfill.
7. Lower the vehicle to the ground and check that it is level. Remove the dipstick and double check the level, adding oil as needed. Reinstall the dipstick securely.
