GT E.T

04 GT's do have 3.55's I'm looking again at work to see if it is an option and on which one if not both (auto manual) did they come in. Didn't you read the MM&FF with the comparo between the cobra, mach 1, and GT?

Yea think about it, the autos always get the short end of everything from Ford...a good example is the auto Mach 1, it is WAY slower than the 5 spds and if I remember correctly it has less power and cant rev nearly as high, so why would ford all of a sudden start giving an auto the advatage of 3.55s without giving it to the 5spds?BTW my 5spd is at around 1800-1900 at 70MPH, and usually they give lower gears to 6s because of the lack of power to help it get up and go....Reminds me, we are changing the gears to 3.73s in my dads 00 V6, and i was wondering if anyone knows how to get the axles out of it, because we just cant seem to find what holds them in there( we already took out the C clips that hold in the third member but that didnt do anything to hold the axles in...or does it)...we changed gears quite a few times in my 66s 8 inch, and pulled the third member out of two 9 inches and changed gears in one of them, as well as calabrated both ourselves by using a thin rag (may sound funny, but an ex funny car driver/mechanic told us how to do it and it works PERFECTLY with very little slack and absolutly NO noise) but this 7.5 is TOTALLY different.Thanks

Both autos and manuals come with 3.27 gears.

Got proof? If you do I'll go jack up my '04 right now and find out.

jack up your rear and have someone rotate the tire around while you lay under the car and let us know what you got?

yeah, MM&FF can nevar be wrong, look at my section in the mail bag where they refuted be for saying the t-3650 has issues (which we all know they do) take magizines with a grain of salt bro, they are glorified catalogs, Yes i'm a subscriber too though

did you take off the brakes any everything too? also, remove the little pinion shaft lock nut(i think that is what it is called) that goes through the center of the diff. it should be between the spider gears. you will see it.

And the final answer is........
































______ manual__ automatic
V-6/GT 3.27:1 __ 2.29:1
Mach 1 3.55:1 __ 2.49:1

Did you say shifting at 5200rpm!!!!!!!!!!!!!!!!!!!!!!! If so thats your problem. Your bogging like hell after every single shift - dropping into the no power range down in the 3ks!! You should be shifting an auto at about 6k (long gears with tendency to bog bad). My car hits about 6300 peak rpm on the shifts.

04 GT's do come from the factory with 3:55 (anniversary pkg/auto's). I have a friend at a dealership that told me this plus I read it in mmff magazine a few issues ago when they raced a mach-1 and cobra...

Are you sure you don't have a V6?? What is your trap speed...there is NO WAY you should be running 16's unless you are at an EXTREMELY high altitude

Ferga: its seems kinda slow even at that altittude. I suggest raising the shift points to 5800 rpms, put the silencer back on. And launch from idle giving it a full throttle stab. Put your tires at the recommended pressure (30-32 psi).
