will it hurt my credit to pay off a car loan early?

Question by : will it hurt my credit to pay off a car loan early?
Bought my car January of 2009.
Payments around $ 300
Left to pay about $ 9000

My credit wasn't very good when I got it so have a high interest rate. I've been working hard to repair my credit/debt situation. I've paid off my debts and made timely monthly paymnts to all creditors, credit cards, car pymnt, etc for atleast a year or two straight now... 2 of my higher limit cards I stupidly closed long time ago not knowing it
