That code says the torque converter clutch is not locking up at the correct speed or not at all. You can drive it but your mileage will suffer. Try this it's called a hard reset Disconnect the negative battery cable and hold it on the positive battery terminal for a minute then reconnect the cable NOTE this will, clear all the presets like radio stations power seat positions ect. This will put all modules back to the original factory specifications. I hope this helps. Take care.
