From the FSM:
2002
1st = 3.416
2nd = 1.944
3rd = 1.258
4th = 0.947
5th = 0.772
6th = 0.630
Final = 4.428
2003
1st = 3.153
2nd = 1.944
3rd = 1.392
4th = 1.055
5th = 0.809
6th = 0.673
Final = 4.133
2004+
1st = 3.153
2nd = 1.944
3rd = 1.392
4th = 1.055
5th = 0.809
6th = 0.630
Final = 4.133
The '03+ are good for turbo. Issue with the '03 inparticular is that its 6th is not as long, but it's nothing huge. Incidentally I have a 03 spec v tranny if someone wants it.
You can identify the tranny by the number on the plate. The 10th digit is the year. So for example, the ’03 I have is: 3N1AB51D4
3L727746. You can see it’s an ’03 tranny because of the “3” in the 10th digit.
EDIT: Thought I would add the B15/P11 ratios as well (again, from the FSM):
1st = 3.333
2nd = 1.955
3rd = 1.286
4th = 0.926
5th = 0.733
Final = 4.437

Above is a good link to look at and compare gearboxes. I love it, personally.
