    Toploader question

    Hi,

    I'm a newbee here and happy to join the 7173 Mustang owner's community.
    I bought a few month ago a 73 Mustang Grandé and start to do some repairing and maintenance on it.

    I have a question about a sensor I broke while removing the gearbox, located on the top left side of it.
    Is it absolutly necessary to have this Transmission-Regulated Spark (TRS system) connected? Cause I can't find any spare parts to replace it. I think this sensor is related to the emission control system.
    In advance thanks for your help,
    Manu

      Never heard of a [TRS system)




      Now I have heard of it, haven't had a car with yet.

              On the Chilton book, there is a chapter about "emission controls". 12 different systems were installing in our cars.
              CVS: Crankcase Ventilastion System (67, 68)
              TAC: Thermactor Air System (1966)
              IMCO: Improved Combustion Emission Control (1968)
              DC: Deceleration Valve (1969)
              DMS: Distribution Modulator System (1970)
              SDV: Spark Delay Valve (71 to 73)
              ERC: Exaust Gas Recirculation (73)
              ESC: Electronic Spark Control (72, for States and Canada)
              TRS: Transmission-Regulated Spark (system I have)
              TAV: Temperature Activated Vacuum (73, 6 cylinders)
              DVS: Delay Vacuum By-Pass (73)
              EEC: Evaporative Emission Controls (69, California)

              I didn't heard about since I broke the sensor on my gearbox. It's always nice to discover new subjects on our cars.
              But unfortunatly, looks like not easy to find a new parts Sad

                Somewhere on this forum a member asked what the little disk was
                connected to the frame by the passenger door. There you have it.

                      Sorry about the inverted image. I'm better with cars than I am with laptops and scanners.
