I wen't to my local nissan dealer and one of the mechanics said it was a 10 hr job at $70 per labor hr. I know it doesn't even take half that long to install these gears. I've noticed in a few threads where people were paying 3-$400 and only took 3 hrs to install, what kind shops will do an install like this instead of the dealership? since i don't wanna spend $700+ for the install.
