I have a 2001 f150 screw with 86000 miles on it. I haven't changed the tranny fluid wanted opinions on weather to change or not. I've been told by several people not to change it that it will start slipping. Have any of you had any kind of problems changing fluid with a lot of miles on it.

 

I doubt you'll have any problems. 86,000 isn't really a lot of miles and I don't really buy into "if it's never been changed don't change it." I mean since when did NEW fluid hurt something?

When I got my truck it had 129,000 miles on it and I'm not sure if the tranny fluid was ever changed before but I changed it and have changed it once a year since I've had it and not one issue.

 

when you hear stories of people changing their fluid and then their car doesnt move.. ive heard it more than a handfull of times..

but at 86K youll be fine to change it.. wouldnt hurt..

 

I've heard that with flushes, but never with just droppin the pan.
