No shifting
DESCRIPTION
•  Single shift range only.
•  Sometimes it shifts correctly.
POSSIBLE CAUSE
•  When the gear position is fixed in 3GR or 5GR* due to the fail-safe operation, malfunction is in the ATX.
•  Perform malfunction diagnosis according to No.6 “LOW MAXIMUM SPEED AND POOR ACCELERATION”.
―  Clutch burnt (C1 clutch, C2 clutch, C3 clutch, B1 brake)
•  Line pressure low
•  Incorrect accelerator opening signal
•  VSS malfunction
•  Input/turbine speed sensor malfunction
•  Sensor ground malfunction
•  Shift solenoid C malfunction
•  Shift solenoid D malfunction
•  Shift solenoid E malfunction
•  Line pressure control solenoid malfunction
•  Shift solenoid F malfunction
•  Control valve body malfunction
―  3GR or 5GR* is fixed (Operation in fail-safe function)
•  Short or open circuit in wiring harness
•  Poor connection of connector
•  Poor ground of shift solenoid
•  Malfunction of electronic parts of output and input system
Note
•  If a tire of a different diameter from the standard tire is installed, the TCM determines that the driving mode is the AAS mode, and may change to a different shift timing from the normal timing.
