Was wondering if anyone out there could help me out. I've lost the window sticker and I believe it had the rearend gears on it. Would really love to know where to find that info. I'd like to get a custom tune for it but need the gear ratio. Any help would be greatly appreciated. The vin is 1ZVFT82H955155639. It's an 05 GT. Thanks - Gabe

 

By window sticker do you mean the one thats on the drivers side door area?

 

......

 

I think for 05's and 06's the auto came with 3.31's and the 5sp came with 3.55's. So thats probally the best way to tell your gear ratio, haha

 

Also if you look at the rear end girdle there should be a label with 3.31 or 3.55 if manual.

 

+1 on both looking at the rearend tag or, if it's gone, find the rear axle code on the door jam sticker.

 

Thanks for the help guys, appreciate your time. The door jam sticker read CG, which should equal out to the 3.31 gears, and since it's an automatic that fits too. Gabe

 

yup thats it!

 

correct the 05 and 06 stock 3.31

 

all factory autos came with the 3.31's

And unfortunately, the rear markings can come off! Mine did!
