ENGAGEMENT CONCERNS: NO FORWARD IN (D) POSITION AND NO REVERSE -207B/307B

Possible Component	Reference/Action
207B - ELECTRICAL ROUTINE
Powertrain Control System
Electrical inputs/outputs, vehicle wiring harnesses, internal transmission wiring harness, PCM, TP, RPM, VSS, EPC	Run Self-Test; REFER to the INTRODUCTION - CNG, FLEX-FUEL & GASOLINE article. Carry out pinpoint tests using the diagnostic tool. Repair as required. Clear DTCs, road test and rerun Self-Test.
307B - HYDRAULIC/MECHANICAL ROUTINE
Fluid
Incorrect level	Adjust to correct level.
Incorrect Pressures
Incorrect band/clutch application pressures, line pressure low, EPC pressure low	Check line pressure at tap. Carry out line pressure and stall speed tests. See the LINE PRESSURE CHART for specifications. If pressure is high/low, check the following possible components: main control, pump assembly.
Filter and Seal Assembly
Filter damaged, plugged; seal damaged, cut or missing	Inspect for damage and install new parts.
Main Control Assembly
Screw out of torque specification	Tighten to specification.
Gasket damaged, 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 electrical routine. Repair as required.
Forward modulator valve/EPC boost valve (207), pressure boost valve (208), EPC blow off valve, 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 damage.
Wrong component used in rebuild	Verify that correct components were used.
Pump Assembly
Screws out of torque specification	Tighten screws to specification.
Cross leaks	Inspect for damage. Repair as required.
Front pump seal worn or damaged	Inspect for damage. Repair as required.
Seal on inner pump gear damaged	Inspect for damage. Repair as required.
Front One-Way Clutch Assembly
Front one-way clutch damaged	Determine cause of condition. Repair as required.
