Sea Foam Official Video: How to add Hydra Trans Tune to automatic transmission fluid


Used as a pre-flush cleaner or shifting problem solver, experienced mechanics and auto parts experts all over North America recommend Hydra Trans Tune as Transmission First Aid for its ability to prevent or overcome sticky and hard shifting problems caused by varnish buildup on transmission system parts.



When added to automatic transmission fluid, Hydra Trans Tune WORKS QUICK to:

  • dissolve and reliquefy harmful petroleum varnish
  • clean valve bodies, fluid passageways, sensors, shift actuators and solenoids
  • condition fluid (prevents varnish buildup)
  • control small amounts of moisture in fluid
  • prevent or overcome operational shifting problems caused by varnish in fluid systems


When replacing transmission fluid, use as a PRE-FLUSH cleaning treatment: 

  • at operating temp, check fluid – Do not exceed manufacturer’s recommended level
  • add up to 1 can (one pint) of Hydra Trans Tune
  • drive at least 30 miles before replacing fluid
  • use each shift gear to circulate the treated fluid


Use as a CLEANING CONDITIONER for the life of the fluid

  • in NEW fluid, add 1 can (one pint) of Hydra Trans Tune to prevent the formation of varnish in fluid
  • add Hydra Trans Tune at ANY TIME to smooth out operational shifting problems caused by harmful varnish buildup


Hydra Trans Tune is SAFE for compatible petroleum fluids- Conventional, Synthetic, Mineral-based

  • will not alter the viscosity of fluids
  • will not harm or swell seals, gaskets, or O-rings (adds petroleum lubrication to polymers/rubber!)
  • does NOT contain detergents or chemicals that can harm transmission system parts


You can find Hydra Trans Tune where automotive products are sold!
