Trans Tune is a petroleum based product comprised of three specific oils, blended in just the right proportions to safely clean varnish deposits in transmission, power steering and hydraulic pump components. Trans Tune is compatible with all commonly used petroleum and synthetic based hydraulic fluids used in automatic transmissions, power steering systems, marine transmissions, agricultural equipment and industrial hydraulic lifts. Trans Tune reduces rough or erratic shifting by dissolving varnish that contaminates transmission valve bodies, bands, governors, pumps and passages. Trans Tune makes the perfect system flush for transmissions, power steering and hydraulic pumps, removing damaging moisture and deposits that impair system performance.
