maxjax tilt and/or autolift

have no personal experience as such, but looking at pics you posted, i think that anything you run with a drill would not be a great deal. why, because think of it this way. the old trans jack with the screw to raise it would take a while to lift. then you are in a hurry so you put air impact on it. if not greased and kept clean i see a chance of it stripping threads if car is over center and trying to raise it. just my opinion.
