Does Not Shift To 7GR Or 8GR
DOES NOT SHIFT TO 7GR OR 8GR (NJ8A(X)-EC/NN8A(X)-EC/MM8A(X)-EC) DESCRIPTION AND POSSIBLE CAUSE
| Description |
- Vehicle does not upshift from 6GR to 7GR or 7GR to 8GR even though vehicle speed is increased.
- At a vehicle speed range where the transaxle should shift up to 7GR and 8GR gears in D position based on the shift pattern, the transaxle does not shift to 7GR and 8GR gears by gradually releasing the accelerator pedal.

| Possible cause |
NOTE:
- When driving on an upslope, downslope, circular road, or at high altitudes, the TCM may determine that the driving mode is AAS mode and set the shift timing different from normal.
- For vehicles with Mi-Drive, when a mode other than NORMAL is selected, a gear lower than NORMAL is selected and the gear is maintained for a longer period of time.
- When the engine coolant temperature is low, the gear is lower than it is in NORMAL mode.
- When driving on slippery roads, 7th and 8th gears may not be selected to assure vehicle stability.
- Input signal malfunction in the following. (See PID/DATA MONITOR INSPECTION
.)
PCM:
- Low-G (XY) sensor (built into SAS control module) malfunction (Refer to [SAS CONTROL MODULE REMOVAL/INSTALLATION
]
).
