VSS switch is almost free (5 bux) but theres a few down sides, Losing the speedo, and if your a automatic locking you in the gear you were when you killed the signal basicly all it dose is throw your car in "limp" mode it thinks its going zero but you still have your tach and u can get a idea on whats goin on..Iv sprayed threw my gov many times with the VSS switch, its kinda tricky with a auto but manuals dont have the gear lock problem
