I know pretty much everybody avoids this, but I guess I'm feeling brave and wondering if anybody out there has changed their automatic transmission. I haven't really paid attention to the tranny when I change the oil, but I'm assuming there is a lower line that can be disconnected to drain into a pan and then I just need to keep putting fluid in the top until it comes out clean. I'm assuming the car would have to be in drive (with the brake set obviously) to make this work. Yes, I'm crazy, but has anybody else tried this? I may have to just finish the diffs and take it somewhere to have the tranny flushed, but my brave side feels like giving it a go.
