Mazda Mazda 3 2015 Mazda 2015 gearbox, engine size 1600. The reason for selling was an electrical problem in the first gearbox. I went to search for the problem, and they said gearbox. I bought this one, and it turned out the old gearbox was fine. I took this one, and its warranty expired. It has been driven 80. Very very very clean. For sale to the highest bidder.
