With the DRBIII
t, Check the STARTS SINCE SET counter for P0714.
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

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 a non-fluctuating DRBIII
t
reading ± 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 40/41TE (NGC) TRANSMISSION VERIFICATION
TEST - VER 1.

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 Powertrain Control Module per the Service Informa-
tion. 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 shorted 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.

Symptom:
P0715-INPUT SPEED SENSOR ERROR
When Monitored and Set Condition:
P0715-INPUT SPEED SENSOR ERROR
When Monitored:
The transmission gear ratio is monitored continuously while the
transmission is in gear.
Set Condition:
If there is an excessive change in the Input RPM in any gear.
POSSIBLE CAUSES
INPUT SPEED SENSOR SIGNAL CIRCUIT OPEN
SPEED SENSOR GROUND CIRCUIT OPEN
INPUT SPEED SENSOR SIGNAL CIRCUIT SHORT TO GROUND
INPUT SPEED SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE
SPEED SENSOR GROUND CIRCUIT SHORT TO VOLTAGE

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 Engine DTC’s. Check and repair all Engine DTC’s prior to
performing any 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 Powertrain Control Module. Some problems are
corrected by software upgrades to the Transmission and Engine software.
NOTE: Check for applicable TSB’s related to the problem.
Perform this procedure prior to Symptom diagnosis.
