ENGAGEMENT CONCERN: DELAYED/SOFT FORWARD AND REVERSE

Possible Component	Reference/Action
209 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical Inputs/Outputs, Vehicle Wiring Harnesses, Powertrain Control Module (PCM), TFT, TSS, Digital TR Sensor, Internal Harness, EPC Solenoid	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 E: ELECTRONIC PRESSURE CONTROL (EPC) SOLENOID . Refer to PINPOINT TESTS - NON OSC EQUIPPED VEHICLES .
309 - HYDRAULIC/MECHANICAL ROUTINE
Fluid
Incorrect level	Adjust fluid to correct level.
Condition	Inspect. 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 linkage, verify that the digital TR sensor is correctly adjusted, refer to TRANSMISSION RANGE (TR) SENSOR ADJUSTMENT .
Incorrect Pressures
