Please do read my post on 2/7 first..Added to this is that you do not have to have it repaired and just stick to using the speed buttons..But, if we do, we can't employ ' yard mode ' in ProCab set up as buttons can not do what wheel does this way...automatic forward/reverse..But, with a small momentum value 1-2 ('0' will torque motor too abbruptly) we can leave speed alone and just hit F & R at will, simulating yard mode..
