Re: 3.42 gears located (Buckmaster)
Just be careful because the rear end diffs on the C5 are known to fail. Some have gone out as early as 3,000 miles. Make sure you know how many miles are on it before you get it and make sure and change out the fluid before installing it. This way you or a tech may be able to tell if the fluid is contaminated or if there is a high presence of metal shavings. This would signal a soon to be defective rear end gear set.
I would say save yourself a headache and get a new set of 3.42 gears.

Picked up a set here on the forum for $500, that was 6000 miles ago. Gears were from a 2001 that had 3500 miles on them. While the car is disassembled throw in a torque converter! You want be sorry!

Re: 3.42 gears located (wallstAL)
I have resisted any performance mods; but this one I would consider. Got a few questions:
A. Do you buy the gears and have them swapped out; or do you buy the entire rear end with the proper gears and swap out the entire assy?
B. I have a 2002 Coupe A4 w/3.15 factory axle.
will 3.42's make a noticeable difference ( I realize going from the 2.73 to 3.42 would make a noticeable improvement)?
C. Do you need to have anything re-programmed?
Thanks

Re: 3.42 gears located (Mike Mercury)
Reprogramming is required for your tranny to shift correctly. Hypertech, Superchips, Powerloader, Custom Tuning (Ed Wright, etc) can handle this for you.
When I purchased my 3.42s, they came as an assembly, which was the bottom half of the diff housing.
The labor on this is pretty high - you really should do a nice street torque converter while you are at it as much of the labor is in common for the two jobs - the converter will make bigger difference then just the gears - I wouldn't even bother with just the gears going 3.15 to 3.42. Get the converter, such as Yank 3000, 3200, or even 3500, and you will have a killer setup that is very well behaved on the street.
I paid $350 for slightly used 3.42s from a gentlemen who was going with a Mallet 3.73 on his M6.
Good Luck

Re: 3.42 gears located (WHY2KRAG)
Great move!!!
I had the 2.73s, car takes off ok until 43 MPH because it drops down to 1st when you hammer it, but after that (like highway speeds) it is soooo slow...
The 3.42s will make a big difference, if you really wanna fly, throw in a converter at the same time (like I did) :D, now it feels like a new car! :yesnod:
