  1. TR_V is the voltage at the PCM pin 19 (TR3A circuit) to signal return.
  2. "In Between" reading could be caused by a selector lever cable or digital TR sensor misaligned or a digital TR sensor circuit failure of TR1, TR2, TR3A or TR4.
  3. TR_D: 1= Open Digital TR switch, 0= Closed Digital TR switch.
  4. Readings taken from PCM signal pins for TR1, TR2, TR3A, TR4 to signal return.
    • Voltages for TR1, TR2, TR4: 
    • 0 = 0.0 volt.
    • 1 = 9.0-14.0 volts.
    • Voltage for TR3A: 
    • 0 = 0.0 volt.
    • 1 = 1.3-1.8 volts.

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 TR_D).
  • 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.
