DIAGNOSTIC ROUTINES REFERENCE

Possible Component	Reference/Action
206 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical inputs/outputs, vehicle wiring harnesses, PCM, Line Pressure Control (LPC) solenoid, Transmission Fluid Temperature (TFT) sensor and Turbine Shaft Speed (TSS) sensor	Run On-Board Diagnostic (OBD). Refer to the INTRODUCTION - GASOLINE MODELS for diagnosis. GO to PINPOINT TEST A , GO to PINPOINT TEST B and GO to PINPOINT TEST C .
Solenoid Body
Incorrect solenoid body strategy data stored in the PCM	Verify solenoid body strategy data stored in the PCM, download new identification and strategy as necessary. Refer to SOLENOID BODY STRATEGY .
306 - HYDRAULIC/MECHANICAL ROUTINE
Transmission Fluid
Incorrect level	Check transmission fluid level and adjust as necessary. Refer to PRELIMINARY INSPECTION .
Condition	Carry out transmission fluid condition check. Refer to PRELIMINARY INSPECTION .
Selector Lever Linkage
Damaged, out of adjustment	Inspect for damage. Repair as required. Verify selector lever cable adjustment. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS - 6F35 .
Incorrect Pressures
Line pressure - low	Check pressure at pressure tap. Carry out Line Pressure and Stall Speed Tests. Refer to SPECIAL TESTING PROCEDURES . See the LINE PRESSURE CHART for specifications. If pressures are low, check the following possible components: main control valve body, pump assembly, and forward clutch.
Main Controls
Plugged solenoid body filter	Inspect for damage. Install new as required.
Bolts out of torque specification	Tighten bolts to specification.
Gaskets and separator plate - damaged, off location	Inspect for damage. Install new as required.
Forward clutch regulator valve stuck or damaged	Inspect for damage. Install new as required.
Forward clutch boost valve stuck or damaged	Inspect for damage. Install new as required.
Main regulator valve - stuck, damaged, missing	Inspect for damage. Repair as required.
Line Pressure Control (LPC) solenoid stuck - low	Inspect for damage. Install a new LPC as required. Refer to SOLENOIDS .
SSA stuck - low	Inspect for damage. Install a new SSA as required. Refer to SOLENOIDS .
Pump Assembly
Bolts out of torque specification	Tighten bolts to specification.
Worn/cross leaks	Inspect for wear and leaks. Install new as required.
Forward Clutch Assembly
Clutch plates, seals, piston - worn, damaged	Inspect clutches, seals and piston for damage. Install new as required.
Wave spring - damaged	Inspect for damage. Install new as required.
