Truck Running bad threw a code!

Can anyone tell me what code 0748 is? My truck is running really bad at low rpm's and it has no low end grunt. So if anyone can help me out that would be great.

P0748 Is a Pressure Control Solenoid Circuit Error. I would tell you what that means but I would only be guessing.
