    4T65-E is the model of your transmission, not a code. Your car has a Hydra-Matic 4T65-E transaxle. Code P1811 means you have to replace the Pressure Control Solenoid Valve Assembly. There are several technical service bulletins on this problem so the dealer may repair it for a reduced cost. I would first try to flush the ATF fluid and install a new filter and clear the code. This may cure the problem and is relatively cheap to do. Good luck!
