Where is the pulse sensor of KIA Maxima gearbox?

You mean the automatic transmission, right? Which pulse sensor are you? There are two sensors on the transmission, one is the input shaft and the other is the output shaft. The input shaft is what we call a turbine sensor. Measuring the rotational speed of the input shaft and the output shaft can determine the gear of the transmission. One is located at the front end of the gearbox and the other is located at the rear end of the gearbox.
