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 - SOFT/SLIPPING

Possible Component	Reference/Action
213 - ELECTRICAL ROUTINE
Powertrain Control System
	Carry out Shift Point Road Test. Refer to ROAD TESTING VEHICLE .
Electrical Inputs/Outputs, Vehicle Wiring Harnesses, Powertrain Control Module (PCM), EPC Solenoid, MAF, TP, ECT, IAT, TFT, Internal Harness, TSS.	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 E: ELECTRONIC PRESSURE CONTROL (EPC) SOLENOID or Go To PINPOINT TEST F: TURBINE SHAFT SPEED (TSS) SENSOR . Refer to PINPOINT TESTS - NON OSC EQUIPPED VEHICLES .
313 - HYDRAULIC/MECHANICAL ROUTINE
Fluid
Incorrect level	Adjust the fluid to the correct level.
Condition	Carry out fluid condition check. For additional information, PRELIMINARY INSPECTION .
Fluid Filter and Seal Assembly
Damaged, partially plugged	Inspect for damage. Repair as required.
Shift Linkage (Internal/External)
Damaged, out of adjustment	Inspect. Repair as required. Verify linkage adjustment. Refer to SELECTOR LEVER CABLE ADJUSTMENT . After adjusting the 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 pressures at line and EPC taps. Refer to SPECIAL TESTING PROCEDURES . If pressures are low or all shifts are soft/slipping; Refer to Main Control - Pump. If pressures are OK and a specific shift is soft/slipping, see the following: Shift Concerns: Soft Shifting: 1-2 - ROUTINE 226/326 Shift Concerns: Soft Shifting: 2-3 - ROUTINE 227/327 Shift Concerns: Soft Shifting: 3-4 - ROUTINE 228/328 Shift Concerns: Soft Shifting: 4-3 - ROUTINE 229/329 Shift Concerns: Soft Shifting: 3-2 - ROUTINE 230/330 Shift Concerns: Soft Shifting: 2-1 - ROUTINE 231/331
