Its time to change my transmission fluid again - After reading on this site for a period of time I would prefer to do it myself - I do not trust the quickie lubes (too many horror stories) but The Ford dealers in my area have differing opinions of what you can useincluding a "universal fluid whatever that is". I know no Mercon 5 - Use Mercon 3. What brands or brand should I use. Should I switch to synthethics - if so who etc - please advise. I plan to use the method of changing fluid that I have read on this site - Thanks for the input
