Abstract:
Various embodiments of methods, apparatus and systems that calibrate main modulation of an electro-hydraulic control system for a vehicle transmission 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 control main valve that develops a control main pressure based upon the main line pressure.
