The word on the street is that if you have a 2009 GT500 that was manufactured after Aug. 15th 2008.....You have the new and improved flywheel. The exact date is a little sketchy and it could vary by a week or 2 plus or minus. The purpose of this thread is to pin that date down for the 2009 GT500 Owners so they know which flywheel is in their car.
The next time you change your oil and have your car in the air, please take a look at your flywheel thru the small drain slot in the bottom of your tranny with a flashlight and verify which flywheel you have and please post your Manufacture Date of your car. The sticker on the door panel will tell you your Manufacture month and your dealer can tell you the exact date by pulling the OASIS report. You will be looking to see if you have vents in the flywheel. Vents are in the old style flywheel and not in the new style flywheel.

Here is a photo photo of the OLD flywheel. The vents next to the center of the flywheel are only on the OLD style flywheel.
Here is a photo of the NEW style flywheel. There are no vents at the center of the flywheel.
Here is a side by side photo of the NEW and the OLD flywheel. The Old flywheel is on the right side. Note the vents in the old flywheel.
Here is the vent slot that you will need to look up into with a flash light. It's right by the oil drain plug in the very bottom of the tranny. if you see just a flat shiney surface inside there....then you have the new flywheel. If you see vents, you have the old style flywheel.
Make sure you are looking in the correct slot on the bottom and not the vent just besides it. This photo points out the right slot to look into. Click on it to enlarge it to see the arrows.
