Sensor assembly and method of assembling a sensor module in a transmission

A transmission comprising:

• a transmission casing having an aperture;
• a sensor module with an elongated, generally cylindrical body having a central axis and configured to extend through said aperture into said casing;
• a bracket connectable to said casing and configured to interfit radially with said sensor module outside of said casing to prevent rotation of said sensor module about said axis when said sensor module is in a first position;
• wherein said bracket is slidable radially away from said sensor module to permit rotation of said sensor module about said axis to a second position without translation of said sensor module along said axis in said aperture;
• and wherein said bracket is further configured to interfit radially with said sensor module to prevent rotation of said sensor module when said sensor module about said axis is in said second position.

A method of assembling a sensor module having a central axis and inserted along said axis through an aperture in a transmission casing comprising:

• loosening a bolt holding a bracket to the transmission casing;
• sliding the bracket relative to the sensor module;
• and
• rotating the sensor module about the axis from a first position to a second position, said positions being established by an interface between said sensor module and said bracket;
• and wherein said rotation from said first position to said second position is accomplished without translating the sensor module along the axis in the aperture.
