DIAGNOSTIC ROUTINES - ENGAGEMENT CONCERN HARSH REVERSE OR FORWARD

Possible Component	Reference/Action
203 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical inputs/outputs, vehicle wiring harnesses, powertrain control module, EPC solenoid, transmission fluid temperature (TFT) sensor, 3-2 timing/coast clutch solenoid (3-2T/CCS)	Run On-Board Diagnostics Tests. Refer to INTRODUCTION - GASOLINE article for Escape (gasoline) and Mariner or INTRODUCTION- HYBRID ESCAPE article for Escape (Hybrid) for diagnosis. GO to PINPOINT TEST B and GO to PINPOINT TEST E .
303 - HYDRAULIC/MECHANICAL ROUTINE
Fluid
Level	Fill to correct level.
Condition	Inspect fluid condition. For additional information, refer to PRELIMINARY INSPECTION .
CV Joints/Front Wheel Driveshaft and Joint
Splines damaged	Inspect for damage. Repair as necessary.
Powertrain Mounts
Loose, broken, missing or misaligned	Inspect mounts. Repair as necessary.
Powertrain contacting other vehicle components	Inspect for contact. Repair as necessary.
External Shift Linkage
Damaged, out of alignment	Inspect and repair as necessary. Verify linkage adjustment. Refer to AUTOMATIC TRANSAXLE-TRANSMISSION EXTERNAL CONTROLS - CD4E . After repairing linkage, verify that the transmission range (TR) sensor is correctly adjusted.
Incorrect Pressures
Incorrect line pressure	Check pressure at line tap. Carry out Line Pressure and Stall Speed Tests. Refer to SPECIAL TESTING PROCEDURES . If high, verify engagements at minimum EPC using the Transmission Tester. If line remains high, check the following components: main control.
Internal Shift Linkages
Damaged, disconnected	Inspect and service as required. If servicing the linkage, verify that the TR sensor is correctly adjusted. Refer to TRANSMISSION RANGE (TR) SENSOR .
