Valve Bodies, Solenoids and Hydraulic System Testing
Technical guides on valve body repair, hydraulic control circuits, solenoids, separator plates, valves, bores, wear points, testing procedures, rebuilding methods, and related replacement parts. This section is designed for transmission rebuilders, valve body specialists, repair shops, suppliers, and parts professionals working with automatic transmission hydraulic control systems.
Automatic transmissions function with the
help of hydraulic pressure to implement the process of gear shifting itself,
and utilize valve body solenoids to handle the pressure of the ATF to specify
the shifting points. There are many solenoids responsible for different gear
shifting operations, and in this article we will have a closer look at
downshifting solenoids.
