Transmission Filters

Unlike oil filters, most transmission filters are located inside the transmission, at the bottom. Many are unusually-shaped metal and/or plastic casings with filter elements inside them.



Transmission filters need to be changed when the transmission fluid is changed. If the dirty filter is left inside, the fine particles that contaminated the old fluid will be passed on to the new fluid.

Most transmission filters are found on automatic transmissions.
