Has code P1811 with a reduced power light as soon as I start the car. I clear the codes and it drives and shifts great. As soon as I shut it off and restart the codes are instantly back and car is shuddering. I am hesitant to replace the pressure solenoid per code P1811. My reasoning is; shouldn't it take at least a moment or two for the ECM to detect this code after clearing it, and not instantly turn on?
have the same problem?
