I feel for you doesn't sound like a lot of fun going on there. 170, 225 or 273? if youre going same to same it should go. not that it matters much but is it a new TC? if so are you positive you have the right unit? funny thing with TC's = they will fight you and fight you and then suddenly it will just punch in there - my last one was on a 360 with a 904 it took two of us nearly a half a case of beer to get that b$%^ch to go! maybe posting a pic or two will help us help you.......
I'm no expert but if nothing else maybe by me answering someone else will chime in. Good luck.
