TRANSMISSION - NGC Symptom: *CHECKING PARK/NEUTRAL SWITCH OPERATION POSSIBLE CAUSES P/N POSITION SWITCH SENSE CIRCUIT OPEN P/N POSITION SWITCH SENSE CIRCUIT SHORT TO GROUND TRANSMISSION RANGE SENSOR POWERTRAIN CONTROL MODULE TEST ACTION APPLICABILITY Ignition on, engine not running. With the DRBIII , monitor the Park/Neutral Position Switch input state. Move the gear selector through all gear positions, Park to 1 and back to Park.
Page 893 TRANSMISSION - NGC *CHECKING PARK/NEUTRAL SWITCH OPERATION — Continued TEST ACTION APPLICABILITY Turn the ignition off to the lock position. Disconnect the PCM harness connectors. Move the Gear selector through all gear positions, from Park to 1st and back. While moving the gear selector through each gear, measure the resistance between ground and the P/N Position Switch Sense circuit in the appropriate terminal of special tool #8815.
Page 894: No Manual Autostick Operation
TRANSMISSION - NGC Symptom: *NO MANUAL AUTOSTICK OPERATION POSSIBLE CAUSES AUTOSTICK DOWNSHIFT SENSE CIRCUIT OPEN AUTOSTICK GROUND CIRCUIT OPEN AUTOSTICK UPSHIFT SENSE CIRCUIT OPEN FUSED IGNITION SWITCH OUTPUT CIRCUIT OPEN PCM - AUTOSTICK TEST ACTION APPLICABILITY Turn the ignition off to the lock position. Disconnect the AutoStick Switch harness connector.
Page 895 TRANSMISSION - NGC *NO MANUAL AUTOSTICK OPERATION — Continued TEST ACTION APPLICABILITY Turn the ignition off to the lock position. Disconnect the PCM harness connector. Disconnect the AutoStick Switch 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.
Page 896: Prndl Fault Clearing Procedure
TRANSMISSION - NGC Symptom: *PRNDL FAULT CLEARING PROCEDURE POSSIBLE CAUSES PRNDL FAULT CLEARING PROCEDURE TEST ACTION APPLICABILITY With the DRBIII , erase Transmission DTCs. Cycle the ignition off, then start the vehicle. Firmly apply the brakes and shift into Overdrive. NOTE: Vehicle must remain in Overdrive for at least 3.0 seconds.
Page 897: Transmission Noisy With No Dtc's Present
TRANSMISSION - NGC Symptom: *TRANSMISSION NOISY WITH NO DTC’S PRESENT POSSIBLE CAUSES INTERNAL TRANSMISSION PROBLEM - NOISY INTERNAL TRANSMISSION PROBLEM - NOISY WHILE STANDING STILL TEST ACTION APPLICABILITY Check and adjust the oil level per the Service Information before continuing. Place vehicle on hoist.
Page 898: Transmission Shifts Early With No Dtc's
TRANSMISSION - NGC Symptom: *TRANSMISSION SHIFTS EARLY WITH NO DTC’S POSSIBLE CAUSES VEHICLE BUS PROBLEMS CHECK FOR INTERMITTENT WIRING & CONNECTORS COLD TRANSMISSION TEST ACTION APPLICABILITY Using the DRBIII , check all other Modules for signs of a PCI bus problem such as bus related DTC’s and/or communication problems.
Page 899: Transmission Simulator 8333 Will Not Power Up
TRANSMISSION - NGC Symptom: *TRANSMISSION SIMULATOR 8333 WILL NOT POWER UP POSSIBLE CAUSES TRANSMISSION SIMULATOR WILL NOT POWER UP TEST ACTION APPLICABILITY NOTE: Make sure to check for any Transmission Control Relay DTCs. or conditions. A stuck open Transmission Control Relay can cause the Trans- mission Simulator to not Power up.
