my LSD is only spinning one wheel so im guessing its on its way out, can i just replace the diff gear ratio and will that fix the issue in most cases? also my gear box is stuffing up and im not sure if its broke, its in limp mode and the soulenoids for 1st 2nd 3ed are stuffing up and not letting the car go in lower gears??? what car fix this, is it more electrical or what??
