Alright Protege geniouses. I need some info on our transmissions. Do all Proteges, Protege5s, MP3s and Mazdaspeeds have the same transmissions? If not, which ones are the same as the Protege5 and which are better, if they would work on the 5. This would pertain to the Manual transmissions. My first and second gear seem to be shot and Mazda is refusing warranty because of my header and cold air intake. Just looking for options on what to do if I have to buy a new transmission. If the transmissions are different between cars, but some are stronger and will work on the 5, which ones?
