How to Put Transmission Fluid in a Car?

Published in Car Maintenance 3 mins read

Adding transmission fluid to your car typically involves locating the transmission fluid dipstick, checking the fluid level, and then carefully adding the correct type of fluid through the dipstick tube using a funnel.

Here’s a step-by-step guide:

  1. Locate the Transmission Fluid Dipstick: The transmission dipstick often looks similar to the engine oil dipstick, but it’s usually located towards the rear of the engine compartment, near the transmission. Refer to your owner's manual if you're having trouble finding it. It commonly has a yellow or orange handle.

  2. Prepare to Check the Fluid: Park your car on a level surface. For an accurate reading, some vehicles need to have the engine running and be in park (check your owner's manual). Engage the parking brake.

  3. Check the Fluid Level:

    • Remove the dipstick and wipe it clean with a lint-free rag.
    • Reinsert the dipstick fully into the tube.
    • Remove the dipstick again and check the fluid level. The dipstick will have "MIN" and "MAX" or "COLD" and "HOT" markings.
    • If the fluid level is below the "MIN" or "COLD" mark, you need to add fluid.
  4. Identify the Correct Transmission Fluid: Refer to your owner's manual to determine the correct type of transmission fluid for your vehicle. Using the wrong fluid can damage your transmission.

  5. Add Transmission Fluid:

    • Purchase the correct type of transmission fluid.
    • Locate the transmission fluid dipstick tube opening.
    • Use a funnel designed for automotive fluids to pour the transmission fluid into the dipstick tube. Add fluid gradually, about ¼ of a quart at a time.
  6. Recheck the Fluid Level:

    • After adding fluid, reinsert the dipstick, remove it, and check the fluid level again.
    • Continue adding small amounts of fluid and rechecking until the fluid level reaches the "MAX" or "HOT" mark on the dipstick.
  7. Clean Up: Once the fluid level is correct, wipe the dipstick clean and reinsert it fully into the tube. Clean up any spilled fluid.

Important Considerations:

  • Automatic vs. Manual Transmissions: The procedure above primarily applies to automatic transmissions. Manual transmissions may have a different fill location, typically a fill plug on the side of the transmission. Consult your vehicle's repair manual for specific instructions.
  • Sealed Transmissions: Some newer vehicles have "sealed" transmissions without a dipstick. Checking and adding fluid to these transmissions typically requires specialized equipment and should be performed by a qualified mechanic.
  • Leaks: If you frequently need to add transmission fluid, it likely indicates a leak. Have your vehicle inspected by a mechanic to identify and repair any leaks.
  • Color and Smell: Pay attention to the color and smell of the transmission fluid. Healthy fluid is typically red and has a slightly sweet smell. Dark, burnt-smelling fluid indicates a problem and may require a transmission service or replacement.
