8. Remove back up lamp switch (2) connector (1).
9. Position transmission jack (2) and secure to trans-
mission (1).
10. Remove transmission to clutch housing bolts.

When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
DTC will set when the transmission temperature does not reach a normal operating temperature within a given
time frame. Time is variable due to ambient temperature. Approximate DTC set time is 10 to 35 minutes. The
following are starting temperature to warm up times to set this DTC: starting temperature -40° C (-40° F) warm
up time 35 minutes, starting temperature -28° C ( -20° F) 25 minutes, starting temperature -6.6° C (20° F) 20
minutes, starting temperature 15.5 ° C (60° F) 10 minutes. When the fault isset, calculated temperature is
substituted for measured temperature, however the DTC is stored only after three consecutive occurrences.

TRANSMISSION TEMPERATURE SENSOR
POWERTRAIN CONTROL MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The temperature sensor is used to sense the temperature of the transmission fluid. Transmission fluid temperature
can affect shift quality, torque converter operation and when or if some diagnostics are run. A failed temperature
sensor could affect the OBD diagnostics. If a problem occurs in the transmission temperature sensor circuit, trans-
mission temperature will be based on a calculated value.

Theory of Operation
Four solenoids are used to control the friction elements (clutches). The continuity of the solenoids circuits are peri-
odically tested. Each solenoid is turned on or off depending on its currentstate. An inductive spike should be
detected by the PCM during this test. If no spike is detected, the circuit istested again to verify the failure. In
addition to the periodic testing, the solenoid circuits are tested if a gear ratio or pressure switch error occurs. In this
case, one failure will result in the appropriate DTC being set. The MIL willilluminate and the transmission goes into
neutral, if the DTC is set above 35 Kmh (22 mph), Limp-in mode when vehicle speed is below 35 Kmh (22 mph).
