I hear that. In my old 64 coupe, 137mph (clock by the local police-no ticket ) was downright scary for a more or less stock vehicle, C4 & 2.75:1 gearing with no performance suspension improvements to speak of. That and the fact the front of the car wanted to lift off.
yeah. the only time i feel my tranny shifting into four gears is when i smash it from a complete stop. other than that i only feel shifting up to third gear. and around 65mph im at roughly 2500rmps. which seems like its in third? my shifter is aligned to the correct slot. how would i adjust it with a pressure gauge?? thanks guys!!
