TRANSMISSION FILTER
The automatic transmission is a mechanical wonder in its design and function,
making your car go forward and backward. The automatic transmission is
nothing more than a giant hydraulic pump that lubricates itself. The fluid follows
a pre-determined path under hydraulic pressure, creating what is called a “fluid
coupling” or linkup between the engine and transmission, propelling the car
forward. In order for all this to happen, the fluid must be clean and flow freely.
The transmission filter plays a major role, keeping the fluid clean of debris such
as dirt, sludge, and clutch material. A clogged filter inhibits the flow of fluid,
causing the pressure to drop, the fluid breaks down, and friction and heat
buildup, which affects the performance of the transmission (or worse, the
transmission fails). It is extremely important to keep the filter and fluid in your
transmission clean.
Recommended replacement interval: Every 25,000 to 35,000 miles.
Proper maintenance is essential if you want to make your car last and save a
lot of money in the long haul. For maximum life, follow the severe service
schedule of your owner’s manual. When the service schedule suggests an
extremely long service interval (in excess of 100,000 miles), get the advice of
your service professional.
