I have a 2004 Corvette and the trouble codes that i am getting are P 0856 and U 1040... Will getting the unit rebuilt solve these issues. There is power to the module that was checked. Thank you in advance

Getting it rebuilt may solve the U1040 code - loss of communication. I doubt it will fix the P0856 code. This could be as simple as a defective TC switch.
