Condition
Some customers may comment on one or more of the following conditions:
-
The shifter binds when putting the vehicle into gear or park.
-
The ignition key sticks or is hard to remove from the ignition lock cylinder.
-
The "Shift to Park" message is constantly displayed on the Driver Information Center (DIC) when the shifter is in the "Park" position.
-
A dead battery that follows after parking the vehicle for an extended period of time (less than 24 hours). This vehicle may have been left in
accessory mode with the "Shift to Park" message displayed.
-
The shifter binds when moving the lever from Drive to Manual mode.
Cause
This condition may be caused by the shift linkage adjustment, a slow Brake Transmission Shift Interlock (BTSI) mechanism or a Park Confirmation
micro-switch that is not closed.
Correction
Adjust the automatic shift linkage following the steps below.
1. Verify the customer's concern.
2. Position the shift lever into the PARK position.
3. Check for any stored diagnostic trouble codes (DTCs). If any codes are set, diagnose the DTCs first using SI.
4. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in SI.
5. Adjust the automatic shift control linkage. Refer to Shift Control Linkage Adjustment in SI.
6. Lower the vehicle.
Tip
If the "Shift to Park" message is displayed, try wiggling or "bumping" the shifter while in the PARK position. If the message goes out, then repeat
the adjustment. This is typically an indicator that the shift linkage is biased rearward. If the initial condition was Drive to Tap Mode binding, then
the shifter linkage was initially biased forward.
7. Determine if the condition has been corrected. If the condition still exists, the automatic transmission shift control may need to be replaced. Refer
to Automatic Transmission Control Replacement in SI.
