Hey Caman, how do you do this?
I have a '96 5.7 4wd 4L60E.
I have Dash Command on my phone.
It works with my blue plastic OBDII gizmo. I have used it to set CKP Cam retard.
But I don't see transmission temp as an available PID.
Got any tips?
Thanks!
TFT sensor is in the 1996 4l60e , its also on the OBD2 broadcast, but I dont remember what it calls it in the menus. TFT is the possible name it may use for what it is. it should follow, gernall, engine running temp, but ideally lower
Transmission Fluid Temperature (TFT) sensor is a negative coefficient thermistor within Transmission Fluid Pressure (TFP) position switch.
TFP is also referred to as Pressure Switch Assembly (PSA). TFT sensor controls signal voltage from PCM. PCM provides a 5 volt reference to sensor on TFT sensor signal circuit. When transmission fluid is cold, sensor resistance is high, and PCM detects high signal voltage. As transmission fluid temperature increases, sensor resistance decreases and voltage decreases. At normal operating temperature of 212°F (100°C), voltage is about 1.5-2 volts. Check sensor for shifted calibration by using sensor TEMPERATURE-TO-RESISTANCE VALUES table. DTC P0712 detects a continuous short to ground in TFT sensor signal circuit or TFT sensor.
