Wow. So I started reading the all the posts in this thread. I had went to the ford site and put this fluid in my cart. I continued reading and went back to the ford site to checkout. I reentered the part number and now there is a message that ford no longer makes this fluid due to low demand.
Guess I'm not trying it now. I h ad the TSB performed last winter. It was immediately better. Prior to TSB I had no 2nd gear when cold. It' still does the nibble though and occasionally gets stuck trying to get 6th.
