Connect your loader to each car seperately and monitor condition of internal relays 581 thru 588. Write down which are set. 581 is park at 1 588 is park at 8 reset the ones you dont want and set the ones you want. I think you can only set one per car. 554 turns off parking feature is reset and turns it on if set. This came off a clip program for an 8 stop inline hydro, but I think the parking program is in the same place for a traction. Post if you have multiple cars and a group controller.
