[QUOTE="Mark Kovalsky, post: 1548032, member: 1654"] Ford wouldn't know the correct fluid to use in their transmission, so don't believe the MERCON V tag. Always believe what you read on the internet above the company that makes the product. [/sarcasm] How old are the things you read that said don't use MERCON V? Before 2006 MERCON V didn't play well with the 4R100. In 2006 Ford changed MERCON V and dropped MERCON, which is what the 4R100 used to use. The newer MERCON V is the correct fluid for the 4R100.
