WTexChevy:
Are you using the governor to switch the overdrive? You can unscrew the governor from the tranny and spin it with a drill to see that it closes the contact to ground. Alternatively, you could bypass the governor and temporarily wire a switch inside the cab that would ground it. When working correctly, I can hear the governor click at 27 mph, then I let off of the gas then reapply and the solenoid does the shift.

Hope this helps.
