TEST

ACTION

APPLICABILITY

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

t PERFORM QUICK LEARN AND

REPROGRAM PINION FACTOR.
Perform 40/41TE (NGC) TRANSMISSION VERIFICATION
TEST - VER 1.

The conditions necessary to set the 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 any problems found?

All

Yes

→ Repair as necessary.

Symptom:

P0870-OD HYDRAULIC PRESSURE TEST FAILURE

When Monitored and Set Condition:

P0870-OD HYDRAULIC PRESSURE TEST FAILURE

When Monitored:

In any forward gear with engine speed above 1000 RPM shortly after

a shift and every minute thereafter.

Set Condition:

After a shift into a forward gear, with engine speed greater than 1000

RPM, the TCM momentarily turns on element pressure to the clutch circuits that don’t
have pressure to verify that the correct pressure switch closes. If the pressure switch does
not close 2 times the DTC sets

POSSIBLE CAUSES

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 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, check for other Transmission DTC’s.

Is the DTC P0944 present also?

All

Yes

→ Refer to the Transmission category and perform the appropriate

symptom.
Perform 40/41TE (NGC) TRANSMISSION VERIFICATION
TEST - VER 1.

→ Go To 3

With the DRBIII

t, read Transmission DTC’s.

Is the DTC P0733 and/or P0871 present also?

All

Yes

→ Replace the Transmission Solenoid/Pressure Switch Assembly per

the Service Information.
Perform 40/41TE (NGC) TRANSMISSION VERIFICATION
TEST - VER 1.

→ Go To 4

With the DRBIII

t, Check the STARTS SINCE SET counter for P0870.

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

All

Yes

→ Go To 5

→ Go To 12

TEST

ACTION

APPLICABILITY

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.
With the Transmission Simulator select the OD Pressure Switch.
With the DRBIII

t, monitor the OD Pressure Switch state in the following step:

Wiggle the wiring and connectors pertaining to this circuit while pressing the
Pressure Switch Test button on the Transmission Simulator.
Did the OD Pressure Switch state change to closed and remain closed while wiggling
the wires?

All

Yes

→ Go To 6

→ Go To 7

If there are no possible causes remaining, view repair.

All

Repair

Disassemble and inspect the Valve Body per the Service Informa-
tion and repair or replace as necessary. If no problems are found in
the Valve Body, replace the Transmission Solenoid/Pressure
Switch Assembly per the Service Information.
Perform 40/41TE (NGC) TRANSMISSION VERIFICATION
TEST - VER 1.

Turn the ignition off to the lock position.
Disconnect the PCM harness connector.
Disconnect the Transmission Solenoid/Pressure Switch Assembly 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.
Measure the resistance of the OD Pressure Switch Sense circuit from the appropriate
terminal of special tool #8815 to the Transmission Solenoid/Pressure Switch Assem-
bly harness connector.
Is the resistance above 5.0 ohms?

All

Yes

→ Repair the OD Pressure Switch Sense circuit for an open.

Perform 40/41TE (NGC) TRANSMISSION VERIFICATION
TEST - VER 1.
