Gears

[01 Yellow GT]

How do you find out what gears you have in your rearend? I have a 2001 yellow GT, stock except for a K&N and a 5-speed.

It should have 3.27's if it's the stock gears. What rpms do you cruise at 70mph ?

If you look at your differential cover, there should be a little metal tag on one of the bolts. It should have some numbers and a letter or two that says what you have. If I remember correctly (this was a year ago), mine said something like "3L27", meaning I had 3.27's. And when I got it apart, I had 3.27 stamped on both my ring and pinion gears. Put in some 4.10's, and you will forget all about those stock ones.

 

[jrc_03_gt]

go with 4.10's 90 MPH @ 3000 RPM'S

 

[Rio97GT]

go with 4.10's 90 MPH @ 3000 RPM'S

You must have a 5-speed because with my auto I'm doing 80 at around 3000RPM.

Either way, you'll love 4.10's if you decide to do gears.

3L27 is, in fact, a 3:27 Locker

 

[jrc_03_gt]

I do have a 5 speed.

He wasn't asking what gears should he get for performance. He was asking what gears does his car have. Dumb asses lol.

I run about 2200 in 5th at 70. I had an idea it was somewhere along those lines. I don't know if I want to tear into that car yet, I have enough junk cars as it is. Well anyway, thanks for all of your input.

 

[Dark Knight GT]

That sounds like 3.27 gears.

 

[Blue02GT]

I have an 02 GT 5 speed, (stock) and at 70 MPH, the Tach is dead on 2000 RPM.

A Calculator can be found here:

If you have the 3650 transmission, the ratios are as follows:

Gear Ratios
1st 3.38
2nd 2.00
3rd 1.32
4th 1.00
5th 0.67
Rev 3.38

By the way, the Mustang doesn't come with a "Locker" rearend. "L" stands for 'Limited Slip'. Similiar but definately not the same thing, and I guess this is what mcmmotorsports meant in his post above.

 

[mcmmotorsports]

Yeah, that is what I meant.
