Started when I was at a light and when it turned green hit the gas and it bogged down...like it was stuck already in a high gear and no matter how far I depressed the gas pedal is wasnt going any faster. Luckily there was another light close. Stopped put it into park and then back into drive...light turns green and now when I hit the girl revs super high like its stuck in 1st and wont shift up. I just replaced the battery so its fresh and new. No prob/trouble codes were triggered that I could hook up my OBDii device and see whats up. Any other thoughts less tragic that can be checked before I get really worried.
