Shift Concerns: Feel - Soft/Slipping

SHIFT CONCERNS: FEEL - SOFT/SLIPPING - DIAGNOSTIC ROUTINES

Possible Component	Reference/Action
213 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical inputs/outputs, vehicle wiring harnesses, PCM, Line Pressure Control (LPC) solenoid, Mass Air Flow (MAF) sensor, Throttle Position (TP) sensor, Engine Coolant Temperature (ECT) sensor, Intake Air Temperature (IAT) sensor, Transmission Fluid Temperature (TFT) sensor, Turbine Shaft Speed (TSS) sensor, Output Shaft Speed (OSS) sensor	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 .
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 .
313 - HYDRAULIC/MECHANICAL ROUTINE
Transmission Fluid
Low transmission fluid level	Check transmission fluid level and adjust as necessary. Refer to PRELIMINARY INSPECTION .
Transmission fluid condition	Carry out transmission fluid condition check. Refer to PRELIMINARY INSPECTION .
Selector Lever Linkage (Internal/External)
Damaged, out of adjustment	Inspect for damage. Repair as required. Verify selector lever cable adjustment. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS .
Incorrect Pressures
Low LPC pressure	Check pressures at line pressure taps. Carry out Line Pressure and Stall Speed Tests. Refer to SPECIAL TESTING PROCEDURES . See the Line Pressure Chart for specification. If pressures are low or all shifts are soft/slipping refer to MAIN CONTROL VALVE BODY .
	If pressures are OK and a specific shift is soft/slipping, see the following chart: Soft/Slipping Shift 1-2, Routine 230/330 Soft/Slipping Shift 2-3, Routine 231/331 Soft/Slipping Shift 3-4, Routine 232/332 Soft/Slipping Shift 4-5, Routine 233/333 Soft/Slipping Shift 5-6, Routine 234/334 Soft/Slipping Shift 6-5, Routine 235/335 Soft/Slipping Shift 5-4, Routine 236/336 Soft/Slipping Shift 4-3, Routine 237/337 Soft/Slipping Shift 3-2, Routine 238/338 Soft/Slipping Shift 2-1, Routine 239/339
Transmission Fluid Filter and Seal Assembly
Plugged, damaged, not correctly seated	Inspect for damage. Install a new filter and seal assembly.
Filter, seal - damaged	Inspect for damage. Install a new filter and seal assembly.
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.
Sticking or binding valves, check balls, clips, springs - damaged, missing	Inspect for damage. Repair or install new as required.
Pump Assembly
Pump assembly - worn/cross leaks, leaking	Inspect for damage. Install new as required.
