SHIFT CONCERNS: FEEL - SOFT/SLIPPING -213/313

Possible Component	Reference/Action
213 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical inputs/outputs, vehicle wiring harnesses, internal transmission wiring harness, PCM, TP, EPC solenoid, TFT, RPM and MAF	Carry out shift point road test. Run on-board diagnostic. REFER to the INTRODUCTION - CNG, FLEX-FUEL & GASOLINE article for diagnosis. Carry out pinpoint tests using the diagnostic tool. Repair as required. Clear DTCs, road test and rerun Self-Test.
313 - HYDRAULIC/MECHANICAL ROUTINE
Fluid
Incorrect level	Adjust fluid to correct level.
Condition	Carry out the fluid condition check.
Incorrect Pressures
Low line pressure	Check pressures at line tap. See the LINE PRESSURE CHART for specifications. If pressures are low check the following components: main controls, filter/seal, pump.
Filter and Seal Assembly
Filter damaged, plugged; seal damaged, cut or missing	Inspect for damage and install new.
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.
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.
Pressure boost valve/main regulator valve (208), EPC blow off valve, extension housing lube orifice, check ball C damaged, spring damaged, missing, misassembled, stuck, bore damaged	Inspect for damage. If damaged install a new main control. If parts are missing install new parts or main control. If misassembled, reassemble correctly. Do not stone, file or sand valves. This will remove the anodized finish and may result in further main control or transmission failure.
