Well it should shift out of overdrive going up hill if it doesn't have enough power. My truck shifts into overdrive at 35 and if I stay at that speed it will wanna go in and out. So normally I stay at a little higher speed like 38 mph. And it shifts out of overdrive up hill. Once it does I click the overdrive button off until I reach the top of a hill then click it back on.

we drive this local route almost daily,and it wasn't a problem before yesterday.it is changing gears every 3 to 5 seconds up,down,up,down etc. until you lock out overdrive with the button.

Well 35mph should be TCC lock up, at 45mph the shift to O/D. If your riding just above and below that point shifting would be normal. I avoid that speed or if trapped behind traffic I lock it out until I can run at a different speed.
Might be the throttle position sensor has a glitch at that point now, a "blip" in the signal causing it to do so. Bad, worn but not enough to trigger a trouble code yet.
If its the problem testing with a analog meter a minute would prove/disprove it, digital meters don't tend to react quick/smoothly enough to properly test one.
