Thanks ZeroZeta.
I used the link you sent me but there is no match for the 370Z trans. I you select 2009 370Z car it says that this part is not compatible. Is this true?

And yes, if you search for the 31935CD80A you will find a sensor that costs more than $100 (for such a little thing).

Just based on the information I get on ebay and Amazon ($20)I was wondering if the sensor sold here the same item was as the one sold by those Nissan specialist websites (>$100).
