INSTRUMENT FOR TESTING A PNEUMATIC CONTROL SYSTEM OF A VEHICLE TRANSMISSION A B S T R A C T A diagnostic instrument detects and locates maufunctions in a pneumatic circuit of the kind which controls a transmission in response to movement of an operator's shift lever. One or more connectors enable simultaneous coupling of a plurality of pneumatic signal lines with various key flow paths of the transmission control circuit. The signal lines extend through a cable to an instrument housing containing a pressure indicator and having a plurality of test valves for sequentially connecting individual ones of the signal lines to the indicator whereby the presence or absence of pressure at various key points in the control circuit may be quickly determined. As the pressures to be detected may be transitory in certain parts of the circuit, means are provided for main- taining the indicator in the pressure indicating condition following a momentary sensing of pressure and reset means are provided for restoring the indicator following testing of each particular flow path so that a subsequent flow path may then be tested. Means are also provided for directing compressed air to any selected one or ones of the circuit flow paths through the test instrument independently of the operator's shift control. Gages are also present on the instrument for determining the exact value of pressures at selected points in the control circuit.
