4R75E - internal wiring harness - TFT sensor
Does anyone have schematic of the wiring harness for 4R75E??
I have a new wiring harness & connector I am planning to install.
Been throwing error code P0712 on occation ("Transmission Malfunction" shows on display). I hit the display button and "Transmission Malfunction" goes away. I was told that the problem is probably with this wiring harness.
I have searched hours and cannot find a schematic and very little information on this issue period. I'm just trying to verify if this wiring harness is the more likely problem ..... or the TFT sensor .... etc.
Thanks in advance for any assistance.
oh .... 2006 F150 SCAB ... 5.4L Lariat Gas ..... tranny code "Q".

Just found this on another forum:
P0712 - Voltage drops across TFT sensor exceeds scale set for temperature of 157 degrees C.
Symptoms = Firm shift feel
RESOLUTION = Replace TFT sensor/wiring

On an '03 F150 on another forum I found this:
"After doing research on-line with the codes I believed that the codes were indicative to the sensor needing to be replaced. I contacted the original mechanic who performed the transmission fluid change and who also detected the codes. I explained to him that the Ford dealer wanted me to pay 1200.00 to tear apart my transmission just too fully diagnose the issue, and NOT fix it. I told him that I believe he was correct when he originally thought it was the sensor and I asked to perform the replacement of the sensor. I took the truck into him and he dropped the transmission pan/fluid and replaced the sensor. After replacing the sensor and putting new fluid back in the transmission, all is working just fine."
