Hello everyone, my 1997 Ford Explorer Sport has never had its transmission fluid changed to my knowledge. I have checked the fluid and it is brown and burnt smelling. The transmission is still functioning as it should right now, so I would like to change the fluid to prevent damage. I am frightened though of the horror stories I’ve heard of high mileage transmission fluid changes. I know that it can be that the only thing keeping a transmission from slipping is the grit in the fluid. I had an idea though, perhaps I could drain the old fluid and keep it. Put in some fresh fluid and see how things go. If the tranny starts acting up I could drain the new fluid and put the old fluid back in. Would that work? Thanks for the input!
