I have a 04 f250 6.0, went to the dealer today to buy coolant to do a flush, then I asked him for a tranny filter and external filter, I wanted to do a tranny change. He asked me how many miles and I told him 140k I just bought the truck a month ago, he said don't change fluid with that many miles, not knowing if fluid was changed before because it might cause problems with seals..... Is this true

 

I have not heard of that. If you just bought the truck, you need to know the status of everything or so I believe. I would go back and get the stuff and do it. Just be sure that when you drop the tranny pan and pull the filter out you make sure that orange gasket gets pulled out with it or after pulling out the filter.

The person who owned mine before didn't do that, so when I pulled my internal filter there were two stuck up in that hole.

Be sure to visit the 6.0 side of this forum.
