TEST ACTION APPLICABILITY
7 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 L/R Pressure Switch Sense circuit from the Pinout Box
to the Transmission Solenoid/Pressure Switch Assembly harness connector.
Is the resistance above 5.0 ohms?
All
Yes → Repair the L/R Pressure Switch Sense circuit for an open.
Perform 41TE (NGC) TRANSMISSION VERIFICATION TEST -
VER 1.
No → Go To 8
8 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 between ground and the L/R Pressure Switch Sense circuit.
Is the resistance below 5.0 ohms?
All
Yes → Repair the L/R Pressure Switch Sense circuit for a short to
ground.
Perform 41TE (NGC) TRANSMISSION VERIFICATION TEST -
VER 1.
No → Go To 9
9 Turn the ignition off to the lock position.
Disconnect the PCM harness connector.
Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.
Remove the Transmission Control Relay.
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.
Connect a jumper wire between the FusedB+ circuit and Transmission Control Relay
Output circuit.
Ignition on, engine not running.
Measure the voltage of the L/R Pressure Switch Sense circuit.
Is the voltage above 0.5 volt?
All
Yes → Repair the L/R Pressure Switch Sense circuit for a short to
voltage.
Perform 41TE (NGC) TRANSMISSION VERIFICATION TEST -
VER 1.
No → Go To 10
