My '03 Explorer XLT V6 has been acting a little odd during slow acceleration from a stop. I can't reproduce this all the time, but sometimes when I start off from a stoplight using very little pressure on the pedal, I'll hear/feel the engine upshift to 2nd and then immediately downshift back into 1st until I pick up another MPH or two, then shift into 2nd again. From there on, it's smooth behavior but this rapid upshift/downshift is kind of annoying and makes me wonder what is going on internally. Any guesses?
