July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Diagnostic Procedure

  1. Using scan tool, read transmission oil temperature. If scan tool temperature reading is above -35°F (-37°C), problem is intermittent. Go to next step.
  2. Disconnect transmission oil temperature sensor connector. Sensor is between pressure filter and cooler line connection. Connect jumper wire between harness connector terminals. If scan tool reads greater than 284°F (140°C), possible poor connection exists or sensor is faulty. Using ohmmeter, inspect sensor and compare readings with TEMPERATURE SENSOR SPECIFICATIONS table. If scan tool reads 284°F (140°C) or less, go to next step.
    TEMPERATURE SENSOR SPECIFICATIONS

    Temperature °F (°C) Ohms
    -40 (-40) 93630
    -20 (-29) 46352
    0 (-18) 24094
    20 (-7) 13111
    40 (4) 7436
    60 (16) 4180
    80 (27) 2554
    100 (38) 1609
    120 (49) 1043
    140 (60) 693
    160 (72) 456
    180 (83) 318
    200 (94) 226
    220 (105) 165
    248 (120) 109
    284 (140) 65
  3. Connect jumper wire between ground and sensor harness connector terminal "A" (Orange/Black wire). If scan tool reads greater than 284°F (140°C), Black wire (terminal "B") is open or PCM is faulty. If scan tool reads 284°F (140°C) or less, Tan/White wire is open or PCM is faulty.
