TRANSMISSION FAILURE MODE EFFECTS MANAGEMENT (FMEM), SHIFT CONCERNS: ERRATIC/HUNTING OR ERRATIC SCHEDULING
| Possible Component | Reference/Action | |
|---|---|---|
| 265 - ROUTINE | ||
| Powertrain Control System | ||
| PCM, vehicle wiring harnesses, transmission internal harness, TSS/intermediate shaft speed sensor, OSS sensor, TR sensor, TFT sensor, TCIL, tow/haul switch, TSPC driver circuit. | Carry out on-board diagnostic tests. Refer to the INTRODUCTION - GASOLINE ENGINES article for diagnosis and testing of the PCM. | |

| Refer to Routine 212. | ||
The transmission FMEM serves 3 purposes:
|
When failures occur the customer may complain of erratic shifting or transmission hanging in gear. This is normal for the FMEM strategy. Determine which gears are being commanded, and which gears are being avoided, and this will in turn point to a specific pressure switch, solenoid or clutch fault. | |
PTO CONCERNS
| Possible Component | Reference/Action | |
|---|---|---|
| 266 - ROUTINE | ||
| Powertrain Control System | ||
| PCM, vehicle wiring harnesses, transmission internal harness, PTO switch, PTO input, parking brake switch, BPP, TFT, TSS sensors required for correct elevated idle and TCC engagements in PARK and NEUTRAL and for correct line pressure | Carry out on-board diagnostic tests. Refer to the INTRODUCTION - GASOLINE ENGINES article for diagnosis and testing of the PCM. | |
| Go to Pinpoint Test B and Go to Pinpoint Test D . | ||
| Repair as required. Clear DTCs, road test and rerun on-board diagnostic test. | ||
ENGAGEMENT SCHEDULE UPDATE (DEAD BATTERY, DISCONNECTED BATTERY, CALIBRATION UPDATED)
| Possible Component | Reference/Action | |
|---|---|---|
| 267- ROUTINE | ||
| Battery | ||
| Any time the vehicle battery has been disconnected, a new PCM has been installed or the vehicle calibration has been reflashed the adaptive strategy for the "Engagement Schedule" will need to be updated. This will prevent the customer from returning with firm engagements. |
NOTE:
All of the following engagements must be carried out in order for engagement pressures to correctly adapt with the new calibration. Once the vehicle's battery has been reconnected or the reprogramming is complete, the adaptive strategy for pressure control on engagements must be updated.
