you don't. the recommended temp for best performance is 120-140*. sure it is safe to run up to 200*, but the transmssion "feels" best at 140 or so. dont get into the power hard either, until the temps have risen.

What is wrong with the Mercon 5?
I had it changed and flushed professionally by a local shop that specializes in Fords and PSD in particular. He was the chief truck mechanic at the local dealership, along with teaching automechanics at the local Technical College so I would have no reason to doubt his judgement. I pulled my 9500 pound 5er for about 11000 miles after the changeover and have had no problems at all....The only reason I sold the V-10 was the fact I got the chance to get this PSD and sold my F250. If I don't use the Mercon 5 what should I use or get him to use when I take it to him tuesday. I want to get the cooler and the fluid change done before Daytona....Thanks for any help...Dave

Not JMO, it's a fact.
