A transmission brake assembly for controlling an output of a transmission of a motor vehicle includes a solenoid which is operatively engagable with a transmission. The solenoid selectively engages and disengages the transmission. A solenoid driver is electrically connected to the solenoid to drive the solenoid into and out of engagement with the transmission. The transmission brake assembly also includes a controller electrically connected to the solenoid driver. The controller turns the solenoid driver between an on state, an off state, and an intermediate state such that the solenoid partially engages the transmission to allow the motor vehicle to move forward at a minimal speed.
