I was driving at 30 MPH and all at once my rpms went high. At that time I had no drive in any forward gear. When I stopped I place it in all drives and reverse and had no drive in any of them. I changed out the vacuum modulator about 3 weeks ago because it was sucking fluid up the vacuum line and it got to the point the explorer did not move. After I changed out the modulator the explorer ran very good. I have check the new modulator and it holds a vacuum. I check out the pressure readings and they are zero at idle and in any gear. Could the pump give out that suddenly or are there other things that could prevent any drive in any gear?
