ok so the car does shift gears, it just happens within maybe 7 feet from a dead stop, doesnt matter if im 1/4-full throttle, it still shifts. i noticed that the two spurs are really loose, like noticably loose. i took the little cover off the top and think that maybe im missing this screw that goes onto the gears shaft? if you look at the tranny from the top, spurs are on your right now, just to the left of the spurs it looks like it would be a set screw to hold the gears to the actually running shaft off the tranny spline. could that be a issue, and how can i make the car shift a little harsher, later. is it possible to make it shift where others noticably hear it shift?. thanks
