The actual module I think your referring to is the TCMA and it is located in the body of the 8HP70 gearbox, it talks to the PCM and other sensors to make things work so in all possibility and with that code I would say a bad connection somewhere .... have no idea where to start looking.
The TCCM, TCMA and PCM all cross reference with other sensors .... this is for the 8 speed though different thing all together for a 5 speeder.... I believe its a seperate bit stashed inside under the dash somewhere but can be incorporated into the PCM, hard to tell as Yank and Export not always the same and I can't remember now which engine.
