milliseconds.
P0963
The transmission control module detects an internal high voltage electrical malfunction of the line pressure control solenoid control circuit for 300
milliseconds.
Action Taken When the DTC Sets
DTC P0961
* DTC P0961 is a Type B DTC.
* The transmission control module freezes transmission adaptive functions.
DTC P0962
* DTC P0962 is a Type A DTC.
* The transmission control module defaults the transmission to 3rd gear.
* The transmission control module commands maximum line pressure.
* The transmission control module freezes transmission adaptive functions.
DTC P0963
* DTC P0963 is a Type A DTC.
* The transmission control module freezes transmission adaptive functions.
Conditions for Clearing the DTC
* DTC P0961 is a Type B DTC.
* DTCs P0962 and P0963 are Type A DTCs.
Diagnostic Aids
When attempting to set solenoid electrical DTCs, ensure the transmission control module is warmed up and the transmission is operated long
enough to ensure a 3掳C (5掳F) increase in transmission control module temperature. This will place the transmission control module under the
optimal conditions to test solenoid electrical DTCs.

Circuit/System Verification
1. Engine ON, verify the transmission fluid temperature is between 50-80掳C (122-176掳F).
2. Operate the vehicle long enough to verify at least a 3掳C (5掳F) rise in TCM temperature parameter, then operate the vehicle in Park for 5
seconds.
3. Engine ON, observe the scan tool Line PC Sol. CKT Status parameter. The reading should display OK or Indeterminate.
瀚慖f the reading is not within the specified range, replace the control solenoid valve assembly.
