well i went to the dealer cause of a checked engine light, and yes i did the ECU codes myself, and came out to be the VSS, but the dealer said that its not the VSS thats in the tranny but its my speedometer head unit, and that it will cost $400+ to fix it and allign it. and i know something's wrong cause i reset the engine light 3 times now, and it always comes back on. Where can i get the head unit, and can i do this myself or do i have to pay the dealer?
