it's not a knock sensor, it's a crank angle sensor. if you expect your car to run right, you might want to drill a hole thru your new tranny's bellhousing and dorp that sensor in.

crank angle sensor = it tells the ecu what 'angle' the crank is at. Essentially, it's just a tool to keep your timing spot-on. making sure your ecu is firing the coil when it should be.
