2005 2.7L V6 AWD automatic with 110,000 miles on it. While driving today all of a sudden it began to shift erratically when starting off from a complete stop. The shifter was in Drive when it happened, but I noticed that if I manually shifted gears it didn't do it. I checked the ATF fluid and it was at the appropriate level and was of good color. Nothing else out of the ordinary. The ATF had 26K miles on it so I changed it as it would be due soon and to see if it made any difference but it did not.

I'm thinking (hoping) something along the lines of a sensor of some kind. Any help/advice is appreciated.
