In my experience, about 150,000 is it. If you are at 170, I'd have it gone through now, so you are not replacing broken pieces or replacing the radiator because tranny debris is in the cooler. You should be able to find a shop who will do a decent job for under $1,500 if the trans is still working properly. Don't make the mistake of waiting until it comes apart.
