My car has an automatic transmission.

Hi there. From what you are saying it sounds like you may have a serious transmission failure. These codes and issues typically comes up when there is excessive slippage indicated in the transmission. It is possible that there is a sensor issue or an issue with voltage. You may also have a module issue or have a connection issue that will cause this. You would be best to have this checked out by a transmission specialist.
