Alright, quick tech question . I was driving today and i put the car in D3, then accelerated to 70 mph. Since the car can't shift into fourth, the rpms climb past 4K, then drop about 200 and then keep climbing. I noticed the drop two spearate times. Both times i was constant on the gas, so i know its not me. It doesn't sound like anythings wrong, just that it is hesitating for some reason. It never does it in D4 though. Does anyone know what might be causing this? Im thinking the computer, but i might be wrong.
