Anyone had any problems with there NNBS GM after getting a converter installed? The code reads TCC Stuck off, the trucks been re-tuned and runs great, but that code is still there......anyone know what it could be, possibley a "selenoid"?

 

i didnt have that code. did yall mess with the valve body? pull the pan and see if theres a harness unplugged or something of the sort.

 

I don't think he did, but I will have to check it out.........
