    2009 624k park brake won’t release

    Thanks will have a look. Where exactly is the TCU located? Seems like it is probably a short in a wire some where considering it kinda fixed itself for a while after I first had the problem

    2009 624k park brake won’t release

    I changed the parking brake solenoid and still won’t release. JD tech support mentioned there could be an update in the computer for the transmission but I’m not sure if that would help the park brake problem any. Any response is greatly appreciated!
