Automatic transmission fluid characteristic monitoring system employed for repair/maintenance and during operation of a land motor vehicle

An apparatus for monitoring the characteristics of an automatic transmission liquid means circulating in an automatic transmission system of a motor vehicle during operation of said motor vehicle, said automatic transmission system comprising

• a conduit means for conducting an automatic transmission liquid means from an automatic transmission to and from a heat exchange means and to said automatic transmission;
• said conduit means having a monitoring means further comprising:
• a sensor means in said conduit means and positioned in a flow path of an automatic transmission liquid means in said conduit means;
• said sensor means, comprising
• a sensor element means responsive to characteristics of an automatic transmission liquid means for providing data corresponding said characteristics of an automatic transmission liquid means;
• and
• a microprocessor means coupled to said sensor means for receiving said data corresponding to said characteristics of an automatic transmission liquid means and converting said data into values corresponding to said characteristics of an automatic transmission liquid means.
