I have a 2009 135i Coupe, Auto Transmission.

First, I noticed my transmission shifts really rough, especially when upshifting at low speed (2nd-3rd most noticable, but it also does it in other gears also), it jerks a little bit, but nothing serious.

I drove a 2013 X5 and 2013 X3 (3.5) and they both shift a lot smoother than mine.

Is this a common problem?

Also, my car is about 36k miles on it, what is the time interval to change transmission fluids?

thank you everyone!

Do you have any warranty left? If you do, I would run to the dealer.
