2006 Mazda3 Grand Touring hatchback, 5-speed AT
While changing the ATF today in my 2006 Mazda3 Grand Touring with the 5-speed Auto transmision, I was surprised/horrified to see an open notch at the bottom of the transmission. I can see inside-- I'm seeing a gear of some sort. 😳 My first thought is, This can't be right-- or even factory-done. It looks like it should have a plastic or rubber cover around it (that has since fallen off). With it open like this, road grit, salt, and rain can get inside. I bought the car a few weeks ago with 230,000 miles. The car runs great (testament to Mazda durability and engineering!). I'll attach a photo and let the resident Mazda3 experts weigh in. While the photo may suggest someone cut it out with a metal saw, I don't think that's the case; the cut is too perfect. And if they did cut it, out... why?! 🤔 Last, there is nothing leaking from the hole and the ATF level stays where it should. It's quite the puzzle.
