Well my check engine light came on, I looked the code up and it says its something to do with the Pressure Control Solenoid A, when It came on I had the O/D light flashing as well then it stopped. Im not really sure what all is going to go into fixing the problem. Im going to clear the code and see if it comes back or not. Anybody ever have this code come up? BTW trans is an auto. Found something here http://www.sctflash.com/PDF/3000-3015 small.pdf page 5 under DTC Says, Pressure control solenoid malfunction.
