Can you drive long enough with the cluster disconnected to see if shifting problems occur?

Is static continuity and resistance testing of wires conclusive if the problem is intermittent?

When I say shifting issues I'm referring to....it feels like it just goes into highest gear and I have no power and then I have to push gas pedal harder then normal to get it to kick down and even at that it seems like it goes to many gears down and engine is tached out way to much.
