Hi - 2011 LX I4 AWD here. In the past week, I've had the car start shifting roughly in all gears twice (including from neutral to drive). Almost like an inexperienced driver on a manual. More pronounced on the lower gears, but definitely present on all gears. Will last for 5-10 minutes of driving, then will suddenly go away. Appeared that the RPMs were 500 or so higher than normal when this was happening and happened in both automatic mode and manumatic mode. Anyone have any ideas as to what's happening? Both times it happened, the car was cold and in morning/evening (when it's colder - that said, I haven't had issues before this past week and it was much colder not too long ago).
