For the past several weeks, occasionally when I first drive in the morning when I get to 30-3me my rpm gauge starts jumping up and down and it sounds like its trying to find a gear or something. Also its seems like its taking a little too long to shift into the higher gears. I had the transmission fluid changed about 4000to miles ago because I was told it was really dirty but I wasn't having problems at that time. I now know there is controversy about changing the fluid. The only code found so far is p0406 for exhaust recirculation. Check engine light is not on.
