Jump, jerk shift up, down then go into 2nd and rest of gears until stop then all repeats on take off. 185k miles shifts fine when cold .Cel is on .
While taking off from stop, engine @operating temp trans will shift 1st-to 2nd on 2002 Chrysler Town & Country
Have it scanned to see why the light is on. Should tell what the trouble is! Trans. will show codes too!
