Hi new here, I have a 2004 mazda 3 with 2.3 engine auto trans,and it has a bad transmission. a friend has a 2004 mazda 3 2.0 engine auto trans with a bad engine and a good trans I can have for free before he junks the car. My question is will the trans from the 2.0 car fit and work right in my car, are they the same or are there differances thanks for any help
