1999 Ford f350 super duty, powerstroke diesel, won't shift into overdrive?

Hi, I purchased a 1999 F350 Super Duty, 7.3L Powerstroke. It had no transmission in it. I bought a used transmission, I was told that it worked fine. I didn't want to chance it, so I had it rebuilt. I put it in a while ago, but never drove it, because I had to replace the water pump. I replaced it, this weekend, and took it out on the road for the first time. It shifted into 2nd gear fine, then into 3rd, but it will not shift into overdrive. Also when I manually shift it, it starts out in first, then I move the shifter into 2nd, it shifts into 2nd, but it also shifts into 3rd when the shifter is still in 2nd. Please let me know if you guys have any ideas. The OD button on the shift lever also seems to work, the off light comes on when I push it, and turns off when I push it again. It doesn't blink at any point.

Does this have the button on the shifter that will turn it on and off try that. If still doesn't work wiring to the solenoid assembly can be a problem. What year was the transmission out of? Wrong year different solenoid assembly. Other problem could be with the button on the column also. Who built the transmission. Take it back to the shop for more help
