2011 Toyota Sienna bought at 97k miles. Unknown maintenance history currently at 106k. Should I drain and fill trans fluid? Drop pan for a deeper clean? Multiple drain and fills to get as much fresh fluid in as possible? Or leave alone? Thank you for your time.

Drain it, drop and clean the pan and put a new filter on it.

I agree with Doc, and from this point onward change the transmission fluid every 40,000 miles.

No idea I haven’t checked it since it’s a “sealed” system. I’m assuming if it’s one of the darker two conditions in the link would me to put the old stuff back in?

Would you ever consider putting used motor oil back in your engine?
