if you go to this link it shows you how much effective tq you have in each gear(which is trans ratio x primary gear x final gear x average tq).so with a little time i adjusted the number to reflect 4.77's in a ap1.this is really so you can see what type of difference the gearing makes on tq since dynos cant measure gear change.
trans gear--4.10--4.77
1st--1937--2252
2nd--1264--1470
3rd--916--1064
4th--718--834
5th--600--698
6th--501--582

Awsome find! Thanks for the link.

Don't forget the reduction gear in the transmission. That needs to be multiplied into the diff results for the total torque multiplication. Also, note that the transmission gears and reduction gear differ in the 00-03 and 04+ cars...

yeah, im wordering if the reduction gear from the ap2 will fit the ap1 tranny

stocky

Better swap the whole tranny

dude were talking about agear that might cost $70 compared to a 1,000+ tranny.i dont know about you but im not rich.i would love the ap2 tranny with the higher 6th gear bu its way out of my price range

2252 what? Lbs. of tq.? Cells per leaf? Buns per package? I'm confussed.

Tq

So in first gear with 4.77 gears you are putting down 2252 ft. lbs of tq.?

Stock AP1 is 2279.78 lb-ft:

153 lb-ft * 4.1* 3.133 * 1.16

1) torque
2) diff ratio
3) 1st gear ratio
4) trans secondary reduction

This ignores drivetrain loss, of course...
