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?

Yeah some point as in after 160,000 mi of never being changed, not some point as in 10,000mi down the road. I think routine maintenance is changing it every 30 or 60000 mi, vehicle depending.
Something about how the transmission wears, then mixes with the fluid, and how if you replaced the fluid you’d lose whatever minor miracle was holding your transmission together
