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?

Basically the question above. I dont understand the reasing behind this. Especially in regard to the heavier weight of campers. Shouldnt it be the other way?
