This just happened to my car...it seems as though your car is missing the automatic shifts huh? When you hit the gas pettle it seems as though it increasing speed but its holding back at the same time...then all of a sudden it all just hits at one time causeing the car to jerk?
If thats what you're experiencing(which is what I experienced) you'll probably get the same codes as me. I got 4 codes that saids my banks were running both too lean and too rich...All in all I needed the transmission rebuilt.
