UNGN,
Hey bro, mine broke too during the TC swap. I found a replacement at the Zone for $23 and some change. You might want to check HiLo and Advanced just to cover the pocket-book.
$$$$$$My local GM dealership was way up there as well $$$$$$.
Oh...almost forgot. When you get ready to replace that metal horse-shoe thingy (the one on the driver's side of the tranny to hold the cable snug), bring your 3 pound hammer under the car with you. It's a tight fit. And don't forget the needle nose to save the fingers.
Good luck.
Erik
