SHIFT CONCERNS: TIMING CONCERNS - EARLY/LATE - 211/311

Possible Component	Reference/Action
211 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical inputs/outputs, vehicle wiring harnesses, internal transmission wiring harness, PCM, TP, TFT, EPC, OSS, RPM and shift solenoids	Carry out shift point road test. Run Self-Test. REFER to the INTRODUCTION - CNG, FLEX-FUEL & GASOLINE article for diagnosis and testing of the Powertrain Control System. Carry out pinpoint tests using the diagnostic tool. Repair as required. Clear DTCs, road test and rerun Self-Test.
Other Electrical Concerns
No power to the PCM. Keep alive memory erased from the PCM	Inspect EEC power relay. Repair as required. Restore memory by carrying out drive cycle test.
311 - HYDRAULIC/MECHANICAL ROUTINE
Engine Driveability Concerns
Vehicle runs poor	See routines 253A, 253B, 353A and 353B.
Other
Tire size change, axle ratio change or speedometer gear change	Verify vehicle has original equipment. See the Certification Label and Safety Standard Certification Label. Changes in tire size or axle ratio will affect shift timing.
Incorrect Pressures
Incorrect band or clutch application pressure, line pressure low (late shift)	Check line pressure at tap. Carry out line pressure and stall speed tests. See PRESSURE CHART for specifications. If the line pressure is low check the following possible component: main control.
Main Control Assembly
Screws out of torque specification.	Adjust screws to specification.
Gasket damaged or off location	Inspect and install a new gasket.
Separator plate damaged	Inspect for damage. Repair as required.
SSA, SSB, SSC, SSD, EPC solenoid stuck, damaged, O-ring damaged or out of bore	Inspect for damage. Carry out solenoid function test as listed in the electrical routine. Repair as required.
Wrong components used during assembly	Verify that the correct components were used.
	Refer to the following shift routine(s) for further diagnosis: Soft/Slipping Shift 1-2, Routine 226/326 Soft/Slipping Shift 2-3, Routine 227/327 Soft/Slipping Shift 3-4, Routine 228/328 Soft/Slipping Shift 4-5, Routine 272/372 Soft/Slipping Shift 5-4, Routine 273/373 Soft/Slipping Shift 4-3, Routine 229/329
