The Trans Tune transmission additive from Sea Foam is another quality product made of three blended oils. The formula is not only effective in tackling transmission related problems, but it also flushes out moisture and damaging deposits found in hydraulic pumps and power steering systems. Trans Tune works with all commercial synthetic and petroleum based hydraulic fluids without altering their viscosity. It also cleans sticky valves and reduces rough shifting thanks to its petroleum-based formula. This quick action fluid conditions automatic transmission fluids and stops oil loss without softening the seals or O-rings.
