How to Replace Transmission Fluid in a Honda Odyssey

by Vanessa Padgalskas

Clean fluid is essential for proper function of the transmission. Changing the transmission fluid every 30,000 miles will keep the transmission running smoothly and prevent major problems. This is an easy process that typically takes less than an hour to complete.

Park the vehicle on a level surface or somewhere that the front end of the Odyssey is lower than the back end so the fluid can drain.

Pop the hood and remove the dipstick. Put the dipstick in a clean place so you don't contaminate the transmission fluid with dust or dirt particles.

Slide under the Odyssey and put a pan under the transmission fluid tank.

Remove the drain plug with a 3/8-inch ratchet. The fluid will drain toward the driver's side; it should take five to 10 minutes to drain completely.

Clean the drain plug with a rag and replace the drain plug on the transmission tank with a new drain plug gasket to prevent leaks.

Measure the amount of transmission fluid that was removed.

Place a small funnel in the dipstick tube and pour transmission fluid into the funnel. You will need the lesser of 3 liters of fluid or the amount that was drained. Do not overfill.

Drive the car for five minutes to let the fluid settle into the tank.

Measure the amount of fluid in the tank by removing the dipstick and making sure the fluid reaches the top line on the end of the dipstick. If the fluid is low, add a little more and remeasure.

Record the transmission fluid change in a maintenance journal as a reminder to complete the process again in 30,000 miles.

Tip

  • Honda recommends using its ATF-Z1 transmission fluid.
