TORQUE CONVERTER OPERATION CONCERNS: NO APPLY - DIAGNOSTIC ROUTINES

Possible Component	Reference/Action
250 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical inputs/outputs, vehicle wiring harnesses, PCM, Torque Converter Clutch (TCC) solenoid, Throttle Position (TP) sensor, Transmission Fluid Temperature (TFT) sensor, Turbine Shaft Speed (TSS) sensor, Output Shaft Speed (OSS) sensor and shorted shift solenoid	Carry out Torque Converter Operation Test. Refer to TORQUE CONVERTER DIAGNOSIS . Run On-Board Diagnostic (OBD). Refer to INTRODUCTION - GASOLINE MODELS for diagnosis. Go To PINPOINT TEST A , Go To PINPOINT TEST B and Go To PINPOINT TEST C .
350 - HYDRAULIC/MECHANICAL ROUTINE
Incorrect Pressures
Line pressure	Check pressure at line pressure tap. Carry out Line Pressure Test. Refer to SPECIAL TESTING PROCEDURES . See the Line Pressure Chart for specifications. If not OK, check Main Control Valve Body.
Main Control Valve Body
Bolts out of torque specification	Tighten bolts to specification.
Gaskets and separator plate - damaged, off location	Inspect for damage. Install new as required.
TCC regulator valve, springs, clips - loose, stuck, missing, misassembled	Inspect for damage. Repair or install new as required.
TCC control valve, springs, clips - loose, stuck, missing, misassembled	Inspect for damage. Repair or install new as required.
TCC solenoid - not functioning correctly	Activate solenoid using scan tool. Refer to OUTPUT STATE CONTROL (OSC) MODE . Go To PINPOINT TEST A . Install a new solenoid body. Refer to SOLENOID BODY ASSEMBLY . Download a new solenoid body strategy into the PCM. Refer to SOLENOID BODY STRATEGY .
