What's my stock gear ratio?

vonblinden22 · 03-12-2010

Does anyone know the stock rear gears on the '08 GTs? (Considering there wasn't a factory upgrade, or whatever.)

stock auto's = 3:31
stock manuals = 3:55

Is that a definite? And is that the same ratio they used in the 05-07s?
The reason I'm asking is because I coulda' swore I read somewhere that they had changed it after 06, possibly for fuel efficiency.

100% positive.....

-------- added 3 Minutes and 42 Seconds later --------

If i am not mistaken, they made changes in the transmissions themselves for better fuel economy......

Heres what I do. Jack up the rearend. Scotch front tires. Mark the back tire and mark the drive shaft and have someone spin the tire one revolution while you watch the drive shaft. If the drive shaft turns 3.5 times then you have a 3:55 gear or 4 times you have a 4:10 gear etc.

Or post the numbers off the tag thats bolted to the rear axle.
