2012 Mazda 3 GS-Sky Sedan
Hi

My GS-Sky is 2 years old in February 2014 and I have 48500Km on it with regular oil changes and scheduled maintenance done on it as per Mazda's suggestions. Recently I've had to have a valve housing inside the tranny replaced by Mazda because it failed. The reason for that was the traction control light came on the car started to rev high and not go anywhere and the AT sign came on as well as the check engine sign. so they replaced the valve housing if Im not mistaken inside the tranny.
Since then the engine has become louder when pressing on the gas and when I switch to Reverse from Park or Neutral the car vibrates hard for a second.
When driving in bumper to bumper traffic and pressing the gas lightly and letting go the car moves forward a few feet then starts to jerk back and forth when I let go of the gas so soon.

any ideas on what could be wrong other than the obvious transmission?

thanks
