Hello there, I just got a new (to me) 2011 ford fusion sel v6 awd it has 129,000 miles on it. I had a question regarding transmission fluid and its maintenance schedule. I checked the fluid and its a little brown, not black and burnt but it looks worn, and by regular convention i would just change it, but i've got a mechanic telling me they're worked on so many ford transmissions and if i change it bad things will happen. Now i dont know the history of when it was changed last but i heard that its around 70k miles so if it was done on that schedule its coming up on its next change. Now you may be asking what i mean by change, i mean dropping the pan, changing the filter and refilling the fluid. So i guess my questions are as follows:
What is the change interval for fluid and filter for this generation?
is changing it at this point going to cause harm?
i know it sounds like a dumb question but i've been getting conflicting answers.
Thanks!
