I purchased a 55 country sedan with a 272 and a Fordomatic. It's a decent car and will be used by my wife to do local home inspection jobs. She mostly wants to use it for advertising and also drive it weekly weather permitting. So here is my question. It is 100% stock and has all the correct linkage for the pressure control for the Fordomatic. It is set correctly but will not shift into high gear. I serviced it and changed the screen. It was clean whenever I did this but did anyway just to look inside. All looks well. The car has sat for many years and I just recently started driving it. My 56 sunliner had the same issue after sitting for 10 plus years during restoration and the Fordomatic in my sunliner was rebuilt about 15 years ago. But sat. Once my sunliner would shift into high 5 to 10 miles after the first drive it shifted fine the whole rest of the day. It finally got to the point where it is not an issue anymore and works fine. I'm about to go out in the wagon and drive it around and see what happens! Thanks in advance for any input or suggestions!
