Today my check engine light came on in my 2002 chevy silverado 1500 4x4. I stopped at a parts place and they hooked up to the computer ind it came back with code P0753 1-2 shift solenoid valve Performance. Dos anyone one where this is? How much will it cost to fix? can i still dive it. it seems fine but it will no kick into o/d on the highway. And is there a trouble shooting like checking for loose wires before fixing it. Please help!!!!
