Transmission problems can be pretty scary. In this case I suspect some dirt in the valve bodyLiterally just got home from a trip and signed on to see if anyone else was having a transmission issue...I'm in normal auto D and when I was flooring it and getting up to a high redline, 7000ish where it would normally shift if I had it floored, well it just sat there and didn't shift. I had to let off the gas in order for it to shift up and then continue accelerating. It has never really done this before at all and is starting to get me worried. It would literally just sit there and let itself keep reving high. I'm very annoyed right now, never had a major issue with me 08 until this, which I consider to be a major issue. I'm going to take it in soon and I hope they don't give me the run around at my dealership like they have before when I notice something but they may not, this is a serious problem.
