Abstract
An automated manual transmission includes a hydraulic device, a pilot valve, and a regulating valve. The pilot valve is operably connected to the hydraulic device and configured to actuate. The pilot valve includes at least one micro-electro-mechanical systems (MEMS) based device. The regulating valve is operably connected to the pilot valve and the hydraulic device. The regulating valve is configured to direct fluid to the hydraulic device based on the actuation of the pilot valve.
