I bought a 2005 Toyota Sienna with 100,000 miles and it runs great. The car doesn't shake or lunges forward when in gear. Shifts smooth and quietly. However, when I purchased the vehicle from a dealership that sells trade-ins...There were no records that the fluid was ever changed. Shall I leave it alone or shall I just go to a transmission place that will change my filter and put the same fluid back in? I don't want to change the fluid and damage the tranny. What should I do?
Yes change the fluid and filter if possible . Save the old fluid if a problem comes up.
If a problem comes up? What damage could be caused?
This is highly doubtful with Toyotas; but with some vehicles if you change the fluid the transmission due to the fluid being smother.
Not changing the fluid will definitely damage it.
always change the filter (if it's replaceable) and clean the pan+magnet.
We bought an 07 Sienna a couple years ago which had 112k on it. No records as well. I had my mechanic change the fluid and filter right after purchasing. Don't flush it. I believe pre-2007 The Sienna's have a timing belt. Make sure if you have have a timing belt get it changed if you are at 100k.
I changed my timing belt, front struts, and front brake rotors with new Akebobo brake pads. My starter went out at 103,000 miles and I replaced that as well.
That's odd the struts and starter went out so early. My uncle has a first year Sienna with over 350k on it and has never replaced anything on it. Not even the timing belt or the oil and filter. One of these days it's going to just fall apart like the Blues Mobile at the end of the Blues Brothers movie.
Change it now, drain and fill only.
So don't save the old fluid? Drain and change the filter? (I know a flush is bad. It damaged my ex-girlfriends car)
Yeup, drain and fill ONLY

😕
no. The point of changing the fluid is to put new fluid in.
Why would you drain something, and then put it back in?

I would still just drain and fill, wouldn't bother with the filter. BUT look at the old fluid when you remove it and also the drain plug for amounts of contaminants. They should give you a better feel for age of fluid and trani condition.
