Most vehicle owner's manuals do not specify a change interval for automatic transmission fluid-unless the vehicle is used for towing. But most transmission experts say changing the fluid and filter (which is located inside the transmission) every 25,000 to 30,000 miles can significantly prolong the life of the transmission. At the very least, the transmission fluid level should be checked periodically. On most vehicles, this should be done after the vehicle has been driven and the fluid is hot. The dipstick is then read while the engine idling and the transmission is in park.
If the level is low, fluid should be added to gradually bring the level up to the full mark-but not overfilled (which can cause the fluid to aerate and foam). If the transmission is leaking fluid from the pan gasket or rear seal, these parts are not difficult or expensive to replace.
Very important! Make sure you get the correct type of fluid for your transmission. Refer to the owner's manual or markings on the dipstick if in doubt.
