Replacing the transmission oil and filter every 30,000 miles will help to keep the automatic transmission in your 2005 Mazda MPV functioning properly. It does not take much to damage a transmission, and driving your MPV when the transmission oil is low due to a clogged transmission filter could lead to serious damage to the transmission. Replacing the filter is a bit laborious, but doing so is absolutely necessary to ensure that your transmission continues to operate properly.
1. Drive the Mazda onto a set of ramps to give you more room to work under the transmission.
2. Place a pan under the drain plug. Remove the plug with a socket and drain the transmission fluid into the drain pan.
3. Remove the bolts that secure the transmission pan to the bottom of the transmission. Pry the pan off the bottom of the transmission.
4. Clean the old gasket material off the pan and transmission using a scraper.
5. Pull the filter off the pickup tube inside the transmission. Press the new filter onto the pickup tube on the transmission.
6. Place the filter onto the transmission pan. Secure the pan to the transmission using the bolts, socket and ratchet. Install the bolts in an alternating pattern.
7. Lift the hood and prop it open. Locate the transmission dipstick near the exhaust manifold on the driver’s side. Remove the dipstick and pour four quarts of ATF transmission fluid into the tube. Reinsert the dipstick in the tube and close the hood.
