i have a gsr tranny housing with si gears inside... i tried using my si VSS and it didnt work, the VSS is fine but the gear is thin and doesnt reach the gears inside im guessing... i compared it to a gsr vss and the gsr vss has a much wider gear on it... but i was scared to put in the vss because i thought maybe it wouldnt grind it... which VSS do i need with the si gears and gsr housing
