Mazda 3 2.0L auto transmission swap to 2.3L, will it fit?

Hello everyone!
I have a 2008 Mazda 3 2.3L Hatchback, really nice car. My transmission starting to go bad.
I had the TCM rebuilt, but that didn't fix my problem. I found a transmission for about $800 with 155k miles, but I don't wanna spend too much money fixing my car. I love this car and don't wanna let it go.
To make this story short, I can get a transmission from a 2011 Mazda 3 2.0L for about $150 with 130k miles.
Now, can I swap the transmission from the 2011 2.0L to my 08 2.3L? Has any one done something like this before?
I know the engine is different, but what about the tranny? I looked at the transmission of the 2011 and it looks the same as mine. Does anyone know if this swap is possible?

My understanding is they are different transmissions, and while they may physically bolt up the same way, the 2011 Mazda3 i transmission will not work in your 2008 Mazda3 s.
