My car has over 260,000 miles. Transmission fluid has never been changed. I asked online general, seems like there is debate. Where on the one hand changing fluid now could do more harm than good. Then others say the transmission fluid has to be changed. I wanted to know what I should do? I just don't want the car to get worse off by changing the Transmission fluid, but if it needs it I'll do it. Thank you for your time.

Yep, that is hard to say, I would always change the fluid because they seem to do better after. They say the clutches might not like it but if this is the case the transmission will start slipping soon anyway. So, it is up to you on want you want to do. Leave it or change it, there might not be a win either way.
