Diagnostic Routine 205/305 - Engagement Concern: Delayed/Soft Reverse

WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.

ENGAGEMENT CONCERN: DELAYED/SOFT REVERSE

Possible Component	Reference/Action
205 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical Inputs/Outputs, vehicle Wiring Harnesses, Powertrain Control Module (PCM), EPC Solenoid, TFT, Digital TR Sensor, Internal Harness	Run On-Board Diagnostic. Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE for diagnosis, Go To PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR , Go To PINPOINT TEST D: DIGITAL TRANSMISSION RANGE (TR) SENSOR or Go To PINPOINT TEST F: TURBINE SHAFT SPEED (TSS) SENSOR Refer to PINPOINT TESTS - NON OSC EQUIPPED VEHICLES .
305 - HYDRAULIC/MECHANICAL ROUTINE
Shift Linkage (Internal/External)
Damaged, out of adjustment	Inspect and repair as required. Verify linkage adjustment. Refer to SELECTOR LEVER CABLE ADJUSTMENT . After adjusting linkage, verify that the digital TR sensor is correctly adjusted; Refer to TRANSMISSION RANGE (TR) SENSOR ADJUSTMENT .
Incorrect Pressures
Low line pressure, low EPC pressure	Check pressure at line and EPC taps. Carry out Line Pressure and Stall Speed Tests. Refer to SPECIAL TESTING PROCEDURES . If pressures are low, check the following possible components: Main Control Valve Body, Pump Assembly, Reverse Clutch Assembly, Reverse Clutch Tube.
Main Controls
Bolts out of torque specification	Tighten bolts to specification.
Gaskets and Separator Plate - damaged, off location	Inspect for damage. Install new as required.
Manual Control Valve, Main Regulator Valve, Converter Drain Back Valve, Springs-missing, damaged, misassembled	Inspect for damage. Repair as required.
Pump Assembly
Bolts out of torque specification	Tighten bolts to specification.
Porosity/cross leaks, pump assembly leaking	Install a new pump assembly.
Gaskets - damaged, off location	Inspect for damage and install new as required.
