What Digitac says about not changing it makes me feel better, but looking at the picture it appears there is some kind of filter medium in between the metal. This makes me think it should be changed at some point.

The OEM filter, that part inside is a metal mesh, like this.

It's a mesh metal filter. You should take a look and determine if you want to change it. At 100k miles, I wouldn't.
So, after doing all this yourself, you don't recommend that others change their filters for preventive maintenance? You recommend drain-and-fills only? If so, sounds good to me!

yes, the filter is like new condition. all the fine metal dust settle at the bottom due to the magnet. if someone have any big piece of metal which couldn't go through the mesh filter, then it's time for a new transmission.
I performed the 3rd drain and fill today. The fluid that came out was a dark red so it looked a lot better than the first two drains. This is now real easy after doing a couple of times. The test drive after the change showed more improvement in the smoothness of the shifting but this time it there was also a noticeably quicker response to stepping on it. The downshift when I stepped on it was much more responsive than it had been with much less lag.

hi digitac. Quick couple of questions.
1. what year was your sc430 that you did a tranny fluid change on?
2. Also I have the 2007 model (6speed), can I drain and refill on that model or not?
3. any pointers or advice on the drain and refill if it is possible on this model?
thanks.
Three years ago when this thread was current, I didn't have much to add. Now, since I've accomplished a 4 qt. drain and fill in my 2008, I have a different perspective. First, notice Toyota calls the tranny "filter" a strainer, not a filter, so no need to change it unless doing repairs on the tranny. Second, I recommend following BWG's procedure detailed in another ATF change thread (search the forum for this). I followed it and it worked like a charm for replacing 4 qts of ATF. If one was to do this every 4-5 years/30-40K miles, I doubt they would ever have tranny issues due to spent ATF.
Even when pulling the pan, you'll likely get no more than a couple of qts out. Thus, removing and adding ATF via the trans cooler lines is recommended to get 4 or more qts out.
