I have a 2013 Dodge Journey 2.4L that is jerking around 3rd gear at idle or when downshifting. When I apply pressure to the peddle to speed up more aggressively there is no issues with shifting at all. There is no jerking when I am aggressively speeding up what so ever but if I am cruising or holding my current speed, it will jerk from time to time. It's more noticeable if I am going uphill. Transmission fluid and filter has been changed but this issue doesn't seem like a Transmission issue as the truck shifts just fine getting up to speed. It only seems to be happening when you are cruising or at idle speed. Any suggestions on this issue? Also there's no fault codes.
