I'm surprised that you had no warnings or nothing, but the fact your transmission Packed it in does not surprise me. The 4T65E that's on the 00-08 Impalas has alot of poor quailty parts and Almost everyone i know has had problems with them. Most of the 00-05 ones seem to last at least 60K but I've noticed quite a few 06+ ones have crapped out in the 30K mark which surprises me. In fact even Mine is giving me problems but I've made it to 95K miles at least. Good luck with yours.
