Abstract:
Various embodiments of methods, apparatus and systems that calibrate main modulation of an elector-hydraulic control system are presented. Some embodiments calibrate regulator control signals that cause a main regulator valve to develop a main line pressure based upon status of a clutch trim valve that develops a clutch feed pressure for a clutch of a transmission.
