first to second it has a jerk, took to Chrysler dealer to have them do a transmission adaptive reset and to see if there were any codes showing up . No codes and they said they tried to do a transmission reset but said it didn't do any good. they couldn't really say what was wrong but that it would be a lot of money to fix. the car shifts fine in all other gears it only jerks when you start of between first and second and when your slowing down from second to first.
