For context: I have an older Toyota 05. 160k miles. Transmission fluid looks kinda brown and mechanic said I should do a flush and quoted me 300$. I’ve also heard that at some point you shouldn’t change the transmission fluid if it has t been changed in awhile. Why is this?

From what I’ve heard, if you haven’t been doing regular “flushes”, then don’t start. It may dislodge some of the dirt or crud and it might find its way into the small nooks and crannies that you don’t want it in. It would be better to do a “drain and fill” instead of a flush. Drain what liquid will come out from the drain hole and then put new transmission fluid in to the proper level. That way you’re not dislodging any of the crud/dirt that has built up over time.
