![]() Some shops offer transmission flushing and filling, which is intended to remove more contaminants than simple draining of the transmission. Although some maintenance schedules may claim that the transmission fluid or filter doesn't need to be changed for the life of the car, remember that the average driving situation falls into the "severe" maintenance category due to short trips and stop-and-go driving. Your car’s automatic transmission filter and fluid should be changed periodically according to the schedule in your owner’s manual. Normally transmission filters trap metal chips from hard parts like gears and bushings and the normal fine material that results from wear of the hydraulic clutch facings and bands. ![]() ![]() Additionally, if a major part fails inside the transmission, the filter may prevent pieces of that part from contributing to a more catastrophic transmission failure. Purpose:Ī transmission filter prevents harmful contaminants from entering the hydraulic system, where they can increase wear and cause scoring and sticking of hydraulic control valves. Different types of filtering media may be used including a fine mesh screen, paper, or felt for filtering media. Transmission Filters: Description:Īutomatic transmissions/transaxles use a filter on the inlet side of the transmission’s hydraulic pump. Consult your technician to see if this can be done. This is also a good time to drain the transmission fluid from the torque converter, if possible. Although changing the fluid yourself is not difficult, it’s probably best left to a qualified service technician. Driving conditions such as trailer towing, quick stops and starts, ascending and descending mountains, and wheel-spinning in slippery conditions are but a few scenarios that can devastate the life of the transmission fluid. The overwhelming majority of transmission failures are heat-related, and automatic transmission fluid breaks down rapidly when subjected to high temperatures. This information can be found in the owner’s manual or on the end of the transmission dipstick. Always use the type of fluid specified by your car’s manufacturer. For best results, have your car’s transmission fluid and filter changed every two years or 40,000 kilometres. Owner’s manual recommendations on transmission fluid changes vary considerably and may go as high as 160,000 kilometres or more. Among other things, it cleans, cools, lubricates, transmits force, transmits pressure, inhibits varnish build-up and protects the transmission on a day-to-day basis. Purpose:Īutomatic transmission fluid serves a multitude of purposes. In all 1983 and later model Ford automatic transmissions use DEXRON ® III/MERCON ® or MERCON ® V Automatic Transmission Fluids. Type F (FLM) is a specially compounded fluid meeting the latest Ford ESW-M2C33F and is compatible with all M2C33 series Ford specifications. automatic transmissions/transaxles where a Chrysler MS-7176, Mopar® or Mopar ATF+3® is specified. It can also be used where fluids meeting Ford ESP-M2C138CJ or Ford M2C166-H specifications are required.ĪTF+3® - Formulated exclusively for Chrysler Corp. Some examples include:ĭEXRON® III/MERCON® - Recommended for all automatic transmissions requiring DEXRON® III, DEXRON® IIE, DEXRON® II, DEXRON® or MERCON ® transmission fluids. There are several different types of automatic transmission fluids and should be used according to the recommendation in your car’s owner’s manual. WHEN TO DO ITĪutomatic transmission fluid is specially formulated oil ™ containing numerous additives to withstand grueling operating conditions. Regular fluid exchanges reduce the build up of contaminants resulting from fluid breakdown caused by heat and debris (such as metal fragments and worn clutch material) within your transmission, which in turn will eventually cause premature wear to moving parts.just like engine oil within your engine but not to the same extent and therefore transmission oil changes are not as frequently required as engine oil changes. Both services include replacement of filter and pan gasket. This process is superior to the Fluid Drain because the "flushing" process replaces 100% of your transmission’s fluid together with a higher degree of sludge and other contaminants. This process replaces only about 40% of your transmission fluid, effectively combining a mix of new and old fluid.įluid Flush - old fluids are "flushed" and exchanged with new fluids using specialized equipment. There are 2 levels of service:įluid Drain - fluids are drained and replaced with new fluids. The process of exchanging old transmission fluid within your automatic transmission with new fluid.
