Hyundai Genesis (DH): Automatic Transmission Control System / Transmission Oil Temperature Sensor Description and Operation
Transmission oil temperature sensor monitors the automatic Transmission fluid's temperature and conveys the readings to TCM.
It is an NTC (Negative Thermal Coefficient) sensor whose
resistance has an inversely proportional relationship with the
temperature level. Data produced by this sensor is used to identify
damper clutch activation and deactivation zones within the low
temperature and high temperature range and to perform hydraulic
amendment control during gear changes.
