I just bought a 98 Taurus and a couple days later it will not shift into what i'm guessing would be 4th. It runs up to 60 like normal and then will not shift. After doing a lot of searching I have found the tranny valve body is a common problem. I saw there was a write up in an older thread on the valve body, but it's missing the pictures. I just wanted to see if you guys think this is the problem or if it would be something else?
