Last night i was driving around and my car seemed to just stall in first gear. Like i have had my rpms drop and my car would recover, but last night the car just began stalling. I know this is a software problem. In disgust, i went home and parked the car. This morning i wake up and take it for a drive and every time i shift from first to second the rear end makes this loud clicking noise. the shifts are smooth so its not like im doing it by shifiting rought. Could this be realted? Please help>? 330zhp.
