    You may need parts changed to make it shift, box install may have robbed power from trans. ECM.

    Check the power steering fluid. I drove a mack with an auto trans. Unless power steering fluid was above min it would hang up in a gear. I don't know why, but it did help. GrAnted it was a piss poor trucking company.

    Sounds about normal for a useless shift… Everyday is different for the trucks I drive with them. Some days they work as they should, other days it can't figure it's way out of a parking spot.
