Reduction Reducing Valve: Outline

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2006 Mazda MPV, 2005 Mazda MPV, 2004 Mazda MPV, 2004 Mazda 6, and 2003 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

The reduction reducing valve reduces the line pressure and adjusts to the reduction reducing pressure allowing the reduction brake to operate at the optimal pressure, while in the forward drive ranges, the line pressure is depressurized by the reduction reducing valve and is applied to the reduction brake. While in R position, the line pressure does not depressurize and is applied to the reduction brake.
