So this car has been shifting weird lately - but it only does it some of the time. The car will randomly decide to start shifting rough, and I mean to the point where it will jitter me in the seat kind of rough - like if you were to take your foot too fast off the clutch after shifting. I used to own a 2013 AT and I remember something similar happening when I first got the car, though it went away after 4,000 miles or so.

I'm kind of just curious as to what the cause of it is though. Today I stopped the car completely when it started happening, turned it off, then turned it back on and it began shifting normally and smooth again. Then randomly it will act up and start shifting rough again - yet the moment I turn the car off and back on it goes back to normal until it decides to start acting up again.

I don't do anything out of the usual. In fact, even when I turn it back to pure automatic mode it shifts rough even in that mode (when the problem starts happening)

It has nothing to do with sports mode/snow mode from my testing of it. It might have something to do with traction on/off but I highly doubt that. I've tried to make it start shifting rough from a bunch of things but it seems to do it by itself randomly. I'm thinking it starts occurring from stop and go (stop signs/red lights for example) then accelerating and stopping again.

My car only has 1300km on it so I'm debating whether waiting to see if it goes away or getting it checked out at a dealer. I'm thinking it's ECU related because all it takes is the car being turned off and back on for the problem to go away until I decide to drive the car for awhile.

I'm contemplating waiting to see if it goes away like my old one did but it's frustrating not knowing what is causing it. Anybody have any ideas?
