Technical Valve Body

The Valve Body is an often source of troubles for transmission repair specialists - here our Team work to provide reliable tips and techniques on this complex unit.



In our last article we talked about transmission solenoid frequency and how it relates to the mechanical response of a solenoid when Pulse Width Modulation (PWM) is used to control a solenoid. We discussed some of the theory, but what does this look like with an actual solenoid? How does frequency affect the response of a solenoid and how critical is matching the OEM frequency when driving a solenoid, especially when we start talking about testing and reclaiming solenoids.
