Default 4+3 OD specs, trouble

What are the guidelines for the OD to engage?
mph
temp
rpm
Also what does the cable do? I asume it kicks it out of OD when you go WOT or does it vary pump pressure or both? I ask cause mine is not working. Last owner said it worked fine till the dash went out. I fixed the dash and now the OD light comes on when you hit the switch but nothing happens. Did the fluid change, the old fluid was like mud didn't look changed in 83k mi. I cleaned and refilled with mobil 1 but still nothing. Could a valve or something be stuck? The cable had full range of motion and everything cleaned up, should I drop the valve body and clean it? Any other things I should try?
