ENGAGEMENT CONCERN: DELAYED/SOFT REVERSE - DIAGNOSTIC ROUTINES

Possible Component	Reference/Action
205 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical inputs/outputs, Transmission Range (TR) sensor, vehicle wiring harnesses, PCM, Line Pressure Control (LPC) solenoid, Transmission Fluid Temperature (TFT) sensor	Run On-Board Diagnostic (OBD). REFER to the INTRODUCTION - GASOLINE MODELS for diagnosis. Go To PINPOINT TEST A , Go To PINPOINT TEST B and Go To PINPOINT TEST D .
Solenoid Body
Incorrect solenoid body strategy data stored in the PCM	Verify solenoid body strategy data stored in the PCM, download new identification and strategy as necessary. Refer to SOLENOID BODY STRATEGY .
305 - HYDRAULIC/MECHANICAL ROUTINE
Transmission Fluid Level
Low transmission fluid level	Check transmission fluid level and adjust as necessary. Refer to PRELIMINARY INSPECTION .
Transmission fluid condition	Carry out transmission fluid condition check. Refer to PRELIMINARY INSPECTION .
Selector Lever Linkage (Internal/External)
Damaged, out of adjustment	Inspect for damage. Repair as required. Verify selector lever cable adjustment. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS .
Incorrect Pressures
Line pressure, LPC pressure - low	Check pressure at line pressure tap. Carry out Line Pressure and Stall Speed Tests. Refer to SPECIAL TESTING PROCEDURES .
