no shift light or tach in it, im just shiftin by engine noise. Its loud enough you can tell when your in the right range or not. You can definatly tell when your lugging it by the noise but not the power, plenty of torque once your rollin
And this is the type of driving i would pull 19 with in my blazer, im not beating on it or anything. But it is running on the warm side, when I get a new fan clutch thrown in it tommorrow, well see if that helps any.
