something is hanging from my transmission????????

[MarketPlayer]

If you have the cvar on a lift and look at the tranny there are three identical sensors that plug into it!  The first two are intact but the third one from the front is dangling on the ground.  It looks as though the wires were cut right at the sensor?  If anyone knows what these things are called, what they do, and how much they cost it would be really helpful!

thanks alot,
