In 2005 and 2006, all Mustang GTs equipped with manual transmissions came with 3.55:1 gears. Now you must specify this option, or your manual transmission 2007 Mustang GT will come with 3.31:1 gears. The order code is 455.

 

why is this...does the 3.31 increase the GT hwy mileage?

 

Sure does, rpms won't be as high...

 

Yea and decrease the fun factor. GO with 4.10's Ford......at least offer them.

 

Yeppir. I ordered my car 3/13 and did not know msrp or cost for the 3.55's. I ordered them anyway. List price as we all now know is $100. This... for what was already included last year.The good news? Because overdrive is now .62 instead of .68... a 2007 Stang with 3.55's will still get better mileage than a 2006 with 3.55's, just not as good as a 2007 with 3.31's. For the illustrations above, we're talking strictly manual transmissions, of course.Can you say... Grabber range? I knew you could!

 

There was a bit of a debate about this on another mustang forum. The general consensus was that this applied to V6's, which currently have the 3.31. You could upgrade them to the 3.55.

Do you have confirmation this is for the GT's too?

 

Not an option on the V6's... only the GT.

 

Here's a link to the 2007 order guide:

Does not apply to Canadian orders.
All Canadian 2007 GTs come with 3.55s.

 

****, I'm jealous. Would've loved to have that color!!!

 

Fuel economy undoubtedly. As to which gears you might want would depend a bit on what you want your Stang to be. If more a long-legged, long-distance, high speed grand touring (GT) coupe, then the 3.31 might not be a bad choice. A bit of a perkier all-arounder, then perhaps the 3.55s for a little more kick. For a short winded quarter horse, then perhaps slipping in a set of 4.10's, albeit with a revving engine on the highway and thirst for the gas.

 

Guess the good news is that there is at least one option, now they need to add a few more. ...just like in the "good ole days"

 

I thought it was the other way around, 05 & 06s came with .62 OD and the 07 has .62 OD (T3650).

 

Hey, Stan, what color did you order?

 

The 4.10's are not that bad, I lost 2 mpg on a drive at 65 mph. I would rather have the 4.10's

 

Wheres the 'welcome to last year' pic

 

For all the people that thought i was dumb asking if it increased gas mileage...i know how gearing works... I know it didn't come out right in the question.


But my real question was if it was rated better mileage from ford. like the 05-06 is 17city-25hwy.

I was wondering if ford did that to increase there fleet average or somthing.

 

I don't know if that's why they did it, but I can tell you this... 17 city is pretty darned high I would say.

Of course I live in Los Angeles which has probably the worst traffic in the country so maybe that's why.

But at the end of the day... I didn't buy the car for the mileage, and I knew that going in. BUT it would be nice to have the best of both worlds

 

When I placed my order, the sales guy actually said "I'm sure you want option 455 also, right?" The only code I didn't have to tell him. Of course I said yes to that one. Now if only I could make them understand what the FRPP handeling Package is.

 

Wow. A salesman who actually knows something.

As for the FRPP handling pack. it can't be ordered with the car. Explain to him it's an accessory as opposed to an option. Options come on the car from the factory. Accessories have to be ordered through the parts department and put on by the dealer or the customer.

If all that was already obvious... oops. Nevermind.
