I just put a deposit on a new 06 GT that my dealer has located, but they can't tell me if the GT automatic comes with a limited slip for the 3.31 axle. The manual which comes with the 3.55 is a limited slip but there seems to be confusion about the automatic. The brochure says it's optional on the automatic, but the dealer has no option code for it. (sorry, no sig yet).

 

I got a GT Premium. It came with a limited slip. I thought it didn't have it and ordered a locker for it, but when they went to install the 3.73s, they said it had it.

Look for the words "trac loc"
