When I bought my car it shifted perfect. Long story made short, rewbuilt engine now 700 miles later the trans shifts funny. I was told by the engine builder that the trans fluid was way over full on the dipstick. Is it possible that the wrong dipstick is in the car and sits too deep inthe trans. That would show normal on stick but actualy too low? Howbad is it to run overfull? If the trans is going out will it go faster if I over fill the fluid?
