Pinpoint Test C : Shift Solenoid C

WARNING: This page is about a different variant/trim than selected.

C1 RETRIEVE AND RECORD ALL DTCS

Using the diagnostic scan tool, retrieve all DTCs.

Are DTCs P0760, P0763, P0764, P0979 and/or P0980 present?

Yes	For DTCs P0760, P0763, and P0764, GO to C2. For DTC P0979, GO to C5. For DTC P0980, GO to C7.
No	GO to Symptom Chart .

C2 CHECK THE SSC CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect: Transmission Vehicle Harness C1520A .

Disconnect: TCM C1750 .

Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.

Measure the resistance between.

Is the resistance between 4.0 and 7.2 ohms?

Yes	INSTALL a new TCM. REFER to Transmission Control Module (TCM) . PROGRAM the TCM with the latest calibration level. PERFORM the Solenoid Body Strategy Download procedure. REFER to Solenoid Body Strategy Download .
No	GO to C4.

C4 CHECK THE SSC RESISTANCE

Remove the solenoid body leadframe, refer to Solenoid Body Leadframe . Inspect for metal shavings on the exposed metal contacts or other components and clean the solenoid and solenoid body leadframe terminals.

Measure SSC resistance between.
