Automatic Trans
My car upshifts all the way into 4th gear well before 30 mph and throttle opening has no effect. Won't downshift even at low speeds. Could this be caused be something other than the computer controls? I have a Predator but it has no effect.

I have seen cars do this right after installing a bigger throttle-body too due t oletting in more air at lower TPS and making more power...
