Abstract
A system controlling gain in a control element includes a source of line pressure, a source of signal pressure, a control valve that controls communication between line pressure and the control element, including a first differential area communicating with control element pressure, and a second differential area, and a gain control valve that opens and closes communication between control element pressure and the second differential area in response to signal pressure.
