My 2005 Mazda 3 shifts better than new.
My 2005 Mazda 3 was having shifting problems and flashing dash gear lights. I was told it's the ECM at a local tranny shop. I then received the refurbished ECM from Flagship One and installed it and had my keys flashed at a local locksmith to the new ECM. I can honestly say that it shifts smoother than the day we got the Mazda new at the dealer. As the car was new, I kind of figured that's the way it is as I had no idea it was controlled by an ECM (I'm old school). As the Flagship One ECM is programmed to your VIN number with updated specs, it works amazing! Thank you, Flagship One, and Kirsten K!
