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.

SHIFT CONCERNS: FEEL - HARSH

Possible Component	Reference/Action
214 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical Inputs/Outputs, Vehicle Wiring Harnesses, Powertrain Control Module (PCM), EPC Solenoid, MAF, TP, OSS, ECT, IAT, PSP, TFT, Digital TR Sensor, Internal Wire Harness and Shift Solenoid No. 3 (SSC), A/C	Run On-Board Diagnostic. Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE for diagnosis. Go To PINPOINT TEST A: SHIFT SOLENOID , 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 E: ELECTRONIC PRESSURE CONTROL (EPC) SOLENOID . Refer to PINPOINT TESTS - NON OSC EQUIPPED VEHICLES .
314 - HYDRAULIC/MECHANICAL ROUTINE
Fluid
Incorrect level	Adjust fluid to correct level.
Incorrect Pressures
High line pressure	Check pressures at line and EPC taps. Carry out Line Pressure Test. Refer to SPECIAL TESTING PROCEDURES . See the LINE PRESSURE CHART . If pressures are high or all shifts are harsh, go to MAIN CONTROL VALVE BODY .
High EPC pressure	If pressures are OK and a specific shift is harsh. See the appropriate shift routine: Shift Concerns 1-2 - ROUTINE 232/332 Shift Concerns 2-3 - ROUTINE 233/333 Shift Concerns 3-4 - ROUTINE 234/334 Shift Concerns 4-3 - ROUTINE 235/335 Shift Concerns 3-2 - ROUTINE 236/336 Shift Concerns 2-1 - ROUTINE 237/337
Main Control Valve Body
Bolts out of torque specification	Tighten bolts to specification.
Gaskets and Separator Plate - damaged, off location	Inspect for damage. Install new as required.
2-3 Capacity Modulator Valve, Main Regulator Valve, Line Modulator Valve, 3-2 Timing Valve, Springs, Clips, Check Balls - stuck, damaged	Inspect. Repair as required.
Pump Assembly
Bolts out of torque specification	Tighten bolts to specification.
Gaskets and Separator - damaged, off location	Inspect for damage. Install new as required
EPC Solenoid - stuck, damaged	Inspect for damage and contamination. Repair as required. Activate the solenoid using the Transmission Tester. If the solenoid operation cannot be felt when placing hand on solenoid, install a new solenoid. Inspect O-rings for damage. Repair as required.
