The EGR hose will usually not have any vacuum until the engine is at least 1500 rpm and the wheels are moving. The computer controls this with an EGR vacuum solenoid. I would check all the vacuum hoses with the under hood vacuum label. The shifting ( OD - drive-OD- Drive) is your Torque Converter Clutch which is controlled by the computer as well, not vacuum.
