How to Add Transmission Oil to an Acura MDX

Adding transmission oil to an Acura MDX is an important step that will ensure that the vehicle's transmission functions properly. Transmission oil, also called transmission fluid, is used to transmit power from the MDX's transmission through the torque converter. The torque converter ultimately transmits the engine power to the drive wheels. While adding transmission fluid to the MDX is rarely necessary, checking the fluid on a routine basis will help you catch small leaks and low fluid levels before they damage the transmission.

Things You'll Need

  • Shop towel
  • Funnel
  • Acura ATF-Z1 transmission fluid

Check the Level

  • Park the Acura MDX on level ground. Start the car and let it run a few minutes until the radiator fan comes on. Turn off the vehicle.

  • Remove the transmission dipstick, which has a yellow handle, and wipe it clean using a cloth.

  • Reinsert the clean dipstick into the transmission until it stops. Allow it to sit momentarily, and then remove it once more.

  • Check the level. The fluid should be between the lower and upper marks stamped in the dipstick. If not, you must add transmission fluid.

Add Transmission Oil

  • Place a funnel into the dipstick hole. This will prevent transmission oil spills.

  • Pour transmission oil down the funnel in small increments. Adding a large amount at one time could result in an overfill.

  • Allow the oil to settle for a few seconds each time you add oil. Then remove the funnel and reinsert the dipstick to check the oil level.

  • Insert the dipstick all the way. Once the transmission oil is between the high and low marks as shown on the dipstick, reinsert the dipstick, making sure it fits securely in the dipstick tube.
