Why do you think you're smarter than the engineers at Ford who programmed the transmission computer? Just leave it "Drive" and let the computer figure it out. Th transmission isn't really an "overdrive", but merely a 4-speed with a higher than usual fourth gear.
Just leave it be - the computer will figure things out better than you can.
The 4th gear ratio of the E40D is 0.71:1. The generally accepted definition of "overdrive" is a gear ratio that gives the transmission output shaft a higher RPM than the input shaft. That's 4th gear in the E40D.
