DIAGNOSTIC ROUTINES - DRIVEABILITY CONCERNS

Possible Component	Reference/Action
256 - ROUTINE
Powertrain Control System
PCM (gasoline engines), Transmission Control Module (TCM) (diesel engines), vehicle wiring harnesses, transmission internal harness, transmission pressure control solenoids, Torque Converter Clutch (TCC) solenoid, Output Shaft Speed (OSS) sensor, Transmission Fluid Temperature (TFT) sensor, tow/haul switch, Accelerator Pedal Position (APP) sensor, Intake Air Temperature (IAT) sensor, Engine Coolant Temperature (ECT) sensor	Carry out On-Board Diagnostic (OBD) tests. Refer to the INTRODUCTION - GASOLINE MODELS for diagnosis and testing of the PCM. For gasoline engines, GO to PINPOINT TEST A , GO to PINPOINT TEST B , GO to PINPOINT TEST D and GO to PINPOINT TEST E . For diesel engines, GO to PINPOINT TEST F , GO to PINPOINT TEST G , GO to PINPOINT TEST I and GO to PINPOINT TEST J . Repair as necessary. Clear the DTCs, road test and rerun OBD test.
Torque Converter
Torque converter internal components damaged	Remove the transmission. Inspect for damage. Refer to TORQUE CONVERTER CONTAMINATION INSPECTION . If the torque converter fails to pass the criteria for replacement or is damaged, install a new or remanufactured torque converter.
Incorrect torque converter used in overhaul	Inspect for correct torque converter assembly. If not correct, install a new or remanufactured torque converter.
