Automobile manufacturers require scheduled transmission fluid
changes in order to maintain warranty coverage. Following the
warranty period, transmission fluid changes are still recommended
on a specific schedule to maintain optimum condition of the
transmission.Transmission coolers, lines and torque converters are not typically drained during a traditional transmission fluid drain and fill. In fact, up to 75% of the used contaminated fluid can remain in the
system. Just like motor oil and engine coolants, transmission fluid
deteriorates over time, forming damaging sludge and varnish
deposits. Wear metals are difficult to remove when much of the old fluid
remains in the transmission system. Much of this damaging debris
stays in the transmission, slowly grinding away internal
components.
According to a leading manufacturer of transmission fluid, the
addition of new fluid to contaminated fluid can actually cause
sludge and varnish deposits to clog filters and restrict the flow of
transmission fluid. This can result in a serious malfunction, or
even a complete transmission failure.
Transmission fluid changing machines that provide a 1:1 exchange
of old and new ATF rely on the vehicle’s transmission pump to
determine the exchange rate and thus the length of time required
to perform the service.The machine removes most of the old, contaminated fluid from
the entire transmission system including the torque converter,
transmission cooler and all transmission lines. The transmission
is then filled with new, OEM-approved automatic transmission
fluid. Even if pan removal is required to replace the filter, the
flush machine can be used to lower the transmission fluid
level for easier, safer and cleaner pan removal.
Automatic Transmission Flushing transforms the old fluid
into a safe cleaner to remove sludge and varnish deposits that
could cause contamination of the new transmission fluid, reduced
ATF flow and cooling, and potential transmission filter plugging.
The  machine makes the removal of suspended
sludge, varnish deposits and wear metals possible, providing
unparalleled maintenance and protection.
Adding  Automatic Transmission Treatment revitalizes
seals and O-rings to help prevent fluid leaks that are common
following traditional transmission fluid changes.
Automatic Transmission Treatment also extends the life of new
transmission fluid to provide better protection between service
intervals.
