Re: any Ford techs that really

Something like this?

Transmission Connector Layouts







Transmission Vehicle Harness Connector







Digital Transmission Range (TR) Sensor Connector












Output Shaft Speed (OSS) Sensor Harness Connector













Turbine Shaft Speed Sensor (TSS) Harness Connector












Digital Transmission Range (TR) Sensor Diagnosis Chart



TR_V is the voltage at the PCM pin 64 (TR3A Circuit) to signal return.
"In Between" reading could be caused by a shift cable or digital TR sensor misaligned or a digital TR sensor circuit failure of TR1, TR2, TR3A, or TR4.
TR_D: 1= Open Digital TR switch, 0= Closed Digital TR switch.
Breakout Box Readings: Taken from PCM signal pins for TR1, TR2, TR3A, TR4 to signal return.
Voltages for TR1, TR2, TR4:
0 = 0.0 volts.
1 = 9.0 - 14.0 volts.
Voltage for TR3A:
o = 0.0 volts.
1 = 1.3 - 1.S volts.
1.8 - 5.0 volts = Invalid reading (open in wires or bad resistor in digital TR sensor).
Wiggle Test Information For Open/Shorts


TR4, TR3A, TR2, and TR1 are all closed in PARK. PARK is a good position to check for intermittent open circuits (with scan tool monitoring TRD).
TR4, TR3A, TR2, and TR1 are all open in OVERDRIVE, so OVERDRIVE is a good position to check for shorts to ground. To determine the shorted components while observing TR_D, unplug the TR and see if the short goes away. If the short is still present, unplug the transmission harness and see if the short goes away. If the short is still present, then the short is in the PCM or vehicle harness. Remove the suspect circuit(s) wire from the PCM vehicle harness. If the short is still present, then the PCM has an internal failure. Otherwise the failure is in the vehicle harness.

Re: Misc. Wiring Diagrams

this has been a very handy link and I would like to share it..it takes time and looking around..but there is a lot of info in this link..

when this link opens.. top center you will see Auto Repair refrence center logo..click on it..when it opens type in the word "Library" for user name and for the pass word.. click on the auto repair refrence again..click in year of truck..then click on Ford, then on Ford F350 super duty then click on select for 7.3 there you will see Repair Topics: Wiring Diagrams and other info can be found there. i hope it helps out...

Hey Dirk,
Great info you posted (the wiring diagram) a week or so ago!

I took your pictures and combined them to make one image...a little bit more readable (hope you don't mind).

Thanks for this information to Dirk and Calico5
