An automatic transmission transfers power from the engine to the rear wheels. It does so by mechanical, hydraulic and mechanical systems of the vehicle. The automatic transmission has hydraulic fluid to lubricate gears and other mechanical components, so as to ensure smooth shift. However, automatic transmissions are not maintenance-free service and must be given regularly. Most automobile manufacturers require automatic transmission fluid and filter changes at regular intervals.


  1. Drive the vehicle to a set of car ramps and put the handbrake. Traces located under the vehicle and the casing of the transmission, which is made of sheet metal and is in the lower part of the transmission. Place a large drain pan under the same pan.
  2. Locate the drain plug on the transmission mounted on the transmission sump. Loosen the cap counterclockwise with a wrench to remove the drain plug transmission available in auto parts stores. Remove the drain plug and set it aside. Let the transmission fluid drain into the pan. Place and tighten again. If your vehicle does not have a drain plug for the transmission, skip this step.
  3. Loosen all the fixing screws of the transmission sump and a ratchet tube. Remove by hand all screws least two. Stop the crankcase with a while you remove the other two screws and lower it by hand. If you salteaste step 2, empty the contents of the pan into the drain pan.
  4. Clean the inside of the pan with a cloth. Remove the existing gasket with a scraper together. Place a new gasket in it, making sure to align the holes in the gasket with the holes in the mounting flange.
  5. Hold the transmission filter, which should be easily visible after removing the crankcase, transmission and remove it with a twisting motion. Pour the liquid into the filter drain pan then get rid of it. Place a new filter in place with a movement circle until it is fully seated.
  6. Place the pan in place and accommodates hand screws. Tighten them in a crisscross with a given pattern and ratchet. To prevent seal damage, do not overtighten the screws.
  7. Open the hood and remove the transmission rod. Place a funnel in the opening of the rod. Pour transmission fluid into the funnel and then remove it. Place the dipstick and check the fluid level. Start the vehicle and let it warm up, then recheck the fluid level. Add just enough to reach the full mark on the dipstick liquid. Close the hood and carefully lower the vehicle ramps.
