Rear Gears

So i had heard that the 3.27 was the stock rear gears for a 2004 auto V6. Does anyone know for sure? or if 3.55 was an option for them?

Also does anyone know a better method of finding out for sure what gears you have? the two ways i have heard of are to drive at about 80 with OD off and whatever your RPMs are at is your gear ratio (e.g. 3500RPM would = 3.55) and of course counting the driveshaft turns per wheel. I havent had a chance to get under the car yet so i've just done the driving one.

I'm sure you have 3:27 gears. 3:55 are not common the only cars I know of that had them were Mach one.

Re: Rear Gears

factory is 3.27 in 99-04, 2.73 in 94-98, and 3.31 in 05+

3.55 is a ratio for 8.8's 3.45 is available for the 7.5 rear as well as 3.73,4.10, 4.56; however none were a factory option for the V6 mustangs, the rangers had 3.73's and 4.10's you can snag and use yourself

if you have the gears out, count the teeth on ring and divide by the # of teeth on the pinion, that gives you the ratio, hence 41/11=3.73 41/10=4.10 etc..

and what you're saying about driving at 80 and checking the engine rpm's is wrong..
80mph with 3.27's in the third gear of an auto (1:1 ratio) would be ~3420rpms
so that is useless to go by
