Manual Valve Body Hard Shifting.

Just purchased a Dodge Dart Sport with a Hurst Promatic 2 shifter, I understand how to shift as I drive a 4 speed on a regular basis. It runs through the gears good when sitting, but when moving, 1st to 2nd is a real chore. However, 2nd to 3rd slides right in. Is this normal or is there an adjustment that can be done to correct it? The transmission has just been completely rebuilt. I googled the shifter and the information provided was minimal at best. Help...my arm hurts!:prayer:
