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.
No
→ 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
No
→ Go To 7
4
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
No
→ 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.
6
Using the schematics as a guide, inspect the wiring and connectors. Repair as
necessary. Pay particular attention to all power and ground circuits.
If there are no possible causes remaining, view repair.
All
Repair
Replace the Transmission Control Module per the Service Infor-
mation. WITH THE DRBIII

The conditions necessary to set this DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this
circuit.
Wiggle the wires while checking for shorts and open circuits.
With the DRBIII
t, check the EATX EVENT DATA to help identify the conditions in
which the DTC was set.
Were there any problems found?
All
Yes
→ Repair as necessary.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.

P0712-TRANSMISSION TEMPERATURE SENSOR LOW
When Monitored and Set Condition:
P0712-TRANSMISSION TEMPERATURE SENSOR LOW
When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
The DTC will set when the monitored Temperature Sensor voltage drops
below 0.078 volts for the period of 0.45 seconds.

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 Service Bulletins related to the symptom.
Perform this procedure prior to Symptom diagnosis.
