K so I need to know which sensor this is, cuz if it's one I can get from advance auto then great but if it's the one I have to get from the dealership then thats' rly going to suck. I know it's the speed sensor but again which one exactly. ALL i know is my ABS, ESP and check engine light came on. This all after I come to a stop light i push on the gas and my car jerks hard. Well I keep going and come to find my car is stuck in first gear and wont change. It's an automatic. I tried the shittronic tring to change gears myself and I couldn't change them that way either. SO i had to drive home with my car reeving at 4thousand the whole time.
