Hi guys, got the engine code p1811. I believe thats the pressure control solenoid?? Now while I'm doing this repair I want to replace other switches likely to go. I'm imagining the shift solenoids, the tcc, the pc, Input speed sensor, and is there anything else? I went onto rock auto, found the solenoids but I wasn't too sure on parts I needed, and which solenoids were which. If some one can give me the part numbers that would be great! thanks!
