Abstract: A calibration apparatus and method (10) for calibrating a hydraulic control valve (40) connected to an electronic controller (20). The electronic controller (20) selects control signals and reads corresponding hydraulic pressure outputs of the hydraulic control valve (40) and selectively records values corresponding to control signals that produce desired calibration pressures.
