Yep, or it will never shift out of first gear at part throttle. Get a red stripe modulator so you can adjust the screw inside it to have some control over shift points.

If you have a manual control valve body, which it sounds as though you do, you shouldn't need a vacuum modulator. Most of the manual valve bodies, just plug off the port. Do you know what brand you are running?
