Default P0700 and P0747 OBDII codes -HELP

I have an '03 silverado 3500 with the 6.6 diesel and the Allison tranny. I noticed a little hesitation and then the light came on, the codes are P0700 and P0745. P0700 says "TRANSMISSION CONTROL SYSTEM", P0747 says"Pressure Control Solenoid 'A' Stuck On". I reset the codes and the light is now off, but I don't think that is the end of it. Any ideas on these codes and the resolution?
