Does anybody know if the 07 GT with an automatic transmission has the limited slip diff? Does it still have the 3:31 to 1 gear ratio?

Thanks

all GTs after 87 have a tlok

I think that GTs still all come with limited slip, but the 3.55 gear is now a $100 option on the 07 GT.
On the 05 and 06 GTs all the diffs were limited slip and the only car that got the 3.55 was a GT, coupe, 5spd. The coupes with autos came with 3.31s and all verts regardless of auto or stick came with 3.31s.

Go to a parking lot with both windows open. Do two slow "figure 8's." Do you hear a "moan" - kinda like your tires rubbing? Then you've just proven to yourself you have a Ford TracLoc. IMO - the noise is normal and don't worry about it.

What gave you that idea?

My door sticker says "CD" which is 3.55:1 - 3:31:1 would be "CG"

Two ways of telling, crawl under the mustang and read the tag bolted to the rear diff. If it says 3L31 or 3L55 then it's a Tracloc. Second method jack up the rear axle until both wheels are off the ground. With tranny in gear rotate one rear wheel and observe the other. If both rotate in same direction then it's a Tracloc. If in oposite directions it's open.

My take is that since the option specifies LS in the 3.55 option then all other axles are open. It wouldn't be the first time Ford changed a standard feature to an option as a method of hidden price increases.

Mine with the 3.31 is a Limited Slip. It lays two nice burnout marks.

This has been a question I've posed to Ford without getting the same answer twice. 2006RedGT, have you confirmed that your pumpkin tag reads 3L31 as opposed to 3 31? What is the axle code on your door tag plate?

Another concern I have is if the rear carrier for the limited slip is the same carrier used back in the '80s and '90s in the Mustangs, Explorers, Broncos and F-150s. They were a real POS. I went through two of them, both self destructing in the same way. I put an Auburn Pro in the back of my C-150 Centurion and haven't had any problems since.

If anyone has torn down a S197 rear end then I ask them to look at the following to see if there are any similarities. Please forgive the rust as I bought the digital camera about a year after destroying the rear end. You will have to use your imagination in piecing it back together.

From what I've read, 06 GT's w/manual came with 3.55,all GT's w/auto came with 3.31
ALL 07's come with 3.31 unless you get the 3.55 option.
