Hello, this should be a 3 speed C6 transmission. The vacuum modulator valve would be located on the right rear corner of the transmission case, above the edge of the transmission. It will have a vacuum hose going to it. Pull of the vacuuum hose and check for any transmission fluid inside the hose, indicating a leak and check for the presence of engine vacuum at the valve while running.
