How to change transmission fluid the right way.

Transmission fluid change: changing transmission fluid is an important job – but it’s one you can do yourself to save money.
Automatic transmission fluid, or ATF, is crucial to the operation of your automatic transmission. Different vehicles have different types of automatic transmissions that require specific types of ATF.

An automatic transmission that shifts roughly, slips or is noisy may benefit from a transmission fluid change. Always check your automatic transmission fluid with the parking brake securely applied and follow your owner’s manual instructions.

Advance Auto Parts carries a wide variety of ATFs and an extensive line of filter kits to suit the needs of your automatic transmission. Our quality auto parts make the task of changing transmission fluid much easier.

Are you changing transmission fluid every 30,000 miles? Here’s why you should.
Your vehicle's fluids perform two vital functions: lubrication and cleaning. As fluid circulates though various parts, it gathers dirt and contaminants that can build up as the engine wears.

Nothing adds longevity to a vehicle's life like regular fluid and filter changes. Your automatic transmission is a complicated component that requires regular care for peak performance. Advance Auto Parts carries automatic transmission fluid, filter gasket kits and other quality auto parts to help you get the job done properly.

How to change transmission fluid on your own – and save money:

Changing transmission fluid can be a messy job. Prepare your work area for drips and spills. Wear gloves and safety goggles.

Unsure of how to change transmission fluid? Follow these step-by-step instructions:

  1. Automatic transmission filter kits usually contain a gasket and O-ring for filter sealing. Your vehicle's kit may be different. Consult your repair manual before attempting this procedure.
  2. Raise and secure the vehicle after warming. Place drip pan under transmission and slowly remove bolts on one side of the transmission pan. Watch for hot surfaces.
  3. Starting closest to the bolts first removed, remove the rest of the bolts. The idea is to get the pan to tilt and drain from one side.
  4. Remove the pan and scrape off any old gasket material from mating surfaces. Then remove the filter and prepare for more fluid! Take note of the filter mounting location.
  5. Install the new filter onto the transmission in the same location as the old one. Make sure all surfaces are free of debris and all fluid passages line up correctly.
  6. After cleaning any debris out of the pan, install the new gasket using a thin film of oil-based grease to keep it attached. Do not use adhesives.
  7. Lift the pan up onto the transmission and install bolts finger-tight. Use a torque wrench and tighten the bolts to manufacturer's specifications in a criss-cross pattern. Safely lower vehicle.
  8. Fill transmission with the recommended type and amount of fluid. Start the vehicle to check for leaks, then check fluid level when the vehicle is warm and in neutral.
