The BB-300 is used on trans brakes that have the ground wire of the solenoid available to the user, also known as a “2 Wire Solenoid”.  The BB-300 interrupts the negative battery voltage signal to the solenoid to allow for precise movement when the “Bump Button” is pressed.  The “Bump” is easily adjustable with two dials on the face of the unit, to allow for easy adjustments without a confusing digital interface.

The Coarse knob increments in 10 millisecond steps, while the Fine knob increments in 3 millisecond steps.
