Re: how i can find out if my car got gears?
Youd have to take off the rear diff cover and look at the pinion. Its usually stamped on the end. Like 273, 355, and so on. if you bought it used then this may be a good idea anyway to get the gear fluid changed, just make sure you get friction midifier, you can get it at any ford dealership for like 3 bucks

Re: how i can find out if my car got gears?
Taking the cover off and changing the fluid probably isn't a bad idea, but if you just want to know if you have gears, try this. Put the rear of the car up in the air, but not supported at the wheels. Put the tranny in neutral and then spin your wheels by hand. Count how many times your driveshaft turns for one revolution of the wheel. If it spins about 3.5 times for one wheel revolution, you probably have a 3.55 gear out back. Get it?

Re: how i can find out if my car got gears?
jacking up the rear and turning the tire one revolution and counting the revolutions on the driveshaft only works if your posi is in great shape. Both wheels have to make 1 complete revolution.
If your posi is fried and only 1 wheel turns counting the revolutions wont work.

Good point, I hadn't thought about that. I guess he can jack it up and try it, but what's the odds of the clutch packs being in good shape in that car? Probably not too good.

Re: how i can find out if my car got gears?
so if both wheels spin the posi is 100% or close to it?
if only 1 spins, the posi is shot?

Re: how i can find out if my car got gears?
If both wheels spin, the clutches/sliders are good enough to hold with the wheels in the air, and almost zero load. Not necessarily 100% or even close to it for that matter. Puttin the horse back on the ground, and putting all the other horses through the driveshaft may say the clutches/sliders are worn out, but it still might have enough grab for this test. On the other hand, if the posi won't grab with the wheels in the air, then it's DEFINITELY worn out. With me?
As far as the test goes, if both wheels spin, it's a very easy way to figure out what gears are back there. I always mark the driveshaft with a grease pencil, inline with a landmark on the diff. case. Works pretty good!

Re: how i can find out if my car got gears?
really you should be able to tell by the way it goes through the gears, especially if its stock, especially if you'v owned other 5.0's.

Re: how i can find out if my car got gears?
4th gear at 55 mph with 2.73 gears will be right at 2000 rpm's with factory height tires.

According to the analyser, you've got 3.08 gears. Stock.
