Transmission fluid begins to break down and lose viscosity
due to time and heat. Fully replacing the fluid in the
transmission prevents transmission slippage, rough shifting
and even failure by preventing the build up of
sludge and varnish which can clog the fluid passages
within the transmission.
It is recommended by the manufacturer to flush the transmission fluids to rid debris and dirt around the seals at different intervals. Regular maintenance to the transmission will avoid premature breakdowns and help make the transmission last longer. The cost of replacing
a transmission in most vehicles today is in the range
of thousands of dollars.
