I have a 1999 Dodge Durango with the 5.2L 4x4. I was wondering if anyone could help me on locate and what type of sensor is located INSIDE the transmission pan or something of that sort. (not really good with auto's) i am not wanting the sensor that is plugged in the back, just the one that is inside the transmission

 

do you know the name of it? what problems are you having?
