If the regular pressure is high will that cause the shift points to be high.. I think it does being that the governor has to match that pressure plus this has the throttle pressure added on to the regulator pressure ... also being this is a stock VB but with the shift improver kit for the 518 it doesnt like to down shift even when I come to a full stop.. I have to manually pull it into low then push the shifter up into drive... thanks for any help....anyone want to BUY a car
