Yes : Refer to the Transmission category and perform the appropriate Symptom. Perform «45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1»(ref-212828-S08485914552005122700000) . No : Go To 2
2. CHECK SHIFTER ADJUSTMENT Check Shifter adjustment. Is the shifter properly adjusted? Yes : Go To 3 No : Adjust the Shifter Assembly. Perform «45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1»(ref-212828-S08485914552005122700000) .
3. 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 EATX DTC EVENT DATA to help identify the conditions in which the DTC was set. If there are no possible causes remaining, view repair. Repair This DTC can be set by putting too much forward pressure on the shift lever while it is in the OD position. Make sure the customer is informed.
