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.

With the DRBIII

t, read the Engine DTC’s.

Are there any Charging System related DTC’s present also?

All

Yes

→ Refer to the Charging System category and repair any PCM

Charging System DTC’s, before testing DTC P0562. NOTE: After
repairing the PCM Charging System DTC’s, perform the Trans-
mission Verification test to verify the transmission was not
damaged.

Turn the ignition off to the lock position.
Disconnect the PCM harness connector.
Note: Check connectors - Clean/repair as necessary.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Using a 12-volt test light connected to 12-volts, check the Ground circuits in the
appropriate terminal of special tool #8815.
NOTE: The test light must illuminate brightly. Compare the brightness to
that of a direct connection to the battery.
Does the test light illuminate brightly for all the Ground circuits?

All

Yes

→ Go To 5

No

→ Repair the Ground circuit and/or circuits for an open or high

resistance.

MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Using a 12-volt test light connected to ground, check the Fused B+ circuit in the
appropriate terminal of special tool #8815.
NOTE: The Test light must illuminate brightly. Compare the brightness to
that of a direct connection to the battery.
Does the test light illuminate brightly?

All

Yes

→ Go To 6

No

→ Repair the Fused B+ Circuit circuit for an open or high resistance.
