I'm going to be changing the automatic transmission fluid in my 03 Ranger 3.0L RWD in the next couple days. I was wondering what kind of fluid you guys are running in your transmissions. I know the book says to use Mercon V but if you've had better results with something else I'd like to know

 

just run that, that's what i run in my 5spd.

 

Mercon V is what I'm using. 200k on the tranny. Still going strong.
