I thought I read recently that the Speed3 doesn't have a dipstick for the transmission. So is there any other way to gauge how much oil we have in the tranny case? I had one for the WRX and I checked it periodically to make sure all was kosher. And it came in handy for when I changed out the fluid. So when it comes time to change out the tranny fluid, do you just fill until it overflows and then put the drain bolt back in?
