does the automatic shift kit shorten the life of the tranny??

It depends on how it is engineered, including the tranny. It used to be back in the dynosaur days, that transmissions were sloppy. By adding a shift kit, the tranny operated more efficiently, therefore, lasted longer. In today's modern space traveling world, the trannys are so well engineered that adding a shift kit could actually shorten its life. All I really can say is you got a 50/50 chance.

I personally don't feel that the Scion tC needs a shift kit, the OEM transmission is set up from the factory the way it is for a reason. If your looking for better shifts, why not upgrade your flywheel (Fidanza) and clutch. (Exedy), (Clutch Masters), (ACT) = Advanced Clutch Technology for example may have what your looking for to upgrade. I'm not saying to not buy a shift kit, its your ride and you can do what you want with it, but as Navy said, if it could lead to a shorter tranny life, me personally, I'd refrain from buying it.
