GA-322 automatic gearbox cleaner/exchanger, before replacing the fuel in the gearbox, will utilize the pressure of the vehicle itself to make a circulatory cleaning to clean the metallic particles, gum and sludge out of the vehicle.

You can add new fuel to the gearbox to restore the accurate performance of the gearbox, reduce the vibration and the fuel consumption.
This is a most effective way to protect the diaphragms inside the gearbox and to extend the gearbox life.
