Symptom:

P0711-TRANSMISSION TEMPERATURE SENSOR PERFORMANCE

When Monitored and Set Condition:

P0711-TRANSMISSION TEMPERATURE SENSOR PERFORMANCE

When Monitored:

Continuously with the ignition on and engine running.

Set Condition:

This DTC will set when the desired transmission temperature does not

reach a normal operating temperature within a given time frame. Time is variable due to
ambient temperature. Approximate times are starting temperature to warm up time: (-40°
F / -40° C - 35 min) (-20° F / -28° C - 25 min) (20° F / -6.6° C - 20 min) (60° F / 15.5 ° C - 10
min)

POSSIBLE CAUSES

TEST

ACTION

APPLICABILITY

NOTE: Low fluid level can be the cause of many Transmission problems. If
the fluid level is low locate and repair the leak then check and adjust the
fluid level per the Service Information.
NOTE: Always perform diagnostics with a fully charged battery to avoid
false symptoms.
With the DRBIII

t, read the engine DTC’s. Check and repair all engine DTC’s prior

to performing Transmission Symptom Diagnostics.
With the DRBIII

t, read Transmission DTC’s. Record all DTC’s and 1 Trip Failures.

NOTE: Diagnose 1 Trip Failures as a fully matured DTC.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Repair as necessary.
Perform the Shift Lever Position Test. If the test does not pass, refer to Symptom test
for P0706 Check Shifter Signal.
For Gear Ratio DTC’s, check and record all CVI’s.
Most DTC’s set on start up but some must be set by driving the vehicle such that all
diagnostic monitors have run.
NOTE: Verify flash level of Transmission Control Module. Some problems
are corrected by software upgrades to the Transmission Control Module.
NOTE: Check for applicable TSB’s related to the symptom.
Perform this procedure prior to Symptom diagnosis.

TEST

ACTION

APPLICABILITY

With the DRBIII

t, check Transmission DTC’s.

Are there any other Transmission Temperature Sensor related DTCs present?

All

Yes

→ Refer to the Transmission category and perform the appropriate

symptom.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.

→ Go To 3

With the DRBIII

t, Check the STARTS SINCE SET counter for P0711.

NOTE: This counter only applies to the last DTC set.
Is the STARTS SINCE SET counter 2 or less?

All

Yes

→ Go To 4

→ Go To 7

Turn the ignition off to the lock position.
Remove the Starter Relay.
CAUTION: Removal of the Starter Relay is to prevent a Transmission, NO
RESPONSE, condition and disable the starter.
Install the Transmission Simulator, Miller tool #8333 and the Electronic Transmis-
sion Adapter kit 8333-1A.
Note: Check connectors - Clean/repair as necessary.
Ignition on, engine not running.
With the Transmission Simulator, turn the Input/Output switch to OFF.
With the DRBIII

t, monitor the TRANS TEMP VOLTS while turning the Thermistor

Voltage switch to all three positions on the Transmission Simulator.
Compare the DRBIII

t readings with the numbers listed on the Transmission

Simulator.
Do the readings on the Transmission Simulator match the DRBIII

t readings ± 0.2

volts?

All

Yes

→ Go To 5

→ Go To 6

If there are no possible causes remaining, view repair.

All

Repair

Replace Transmission Solenoid/TRS Assembly per the Service
Information.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.
