CHECK CUSTOMER DRIVING HABIT
This DTC can be set if the customer rests their hand on the shift lever while they are driving. The transmission can be put in the T3 position if just enough forward pressure is exerted on
the shift lever.
When this occurs, the feed port to the clutch is restricted, the transmission will declare neutral, and this DTC will be set. The customer should be informed not to rest their hand on the shifter
while driving.
This DTC can also be set by simply bumping the shift lever toward neutral while accelerating.
With the scan tool, check the DTC EVENT DATA to help identify the conditions in which the DTC was set.
If there are no possible causes remaining, view repair.
