It is important
to wash the automatic transmission because, exactly like the other mechanical
compounds, it generates friction inside it, putting a number of impurities into
circulation. To wash the internal part of the automatic transmission it must be
completely unassembled with specific machineries, oils and additives. The oil
of the automatic transmission tends to become more dense and to lose its
properties, so it is better to replace it.
kinds of driving influences the change of the oil; if you drive in the city it
will be necessary to change it more often because its compounds are affected by
more stress and so they will wear out quickly.
