Gear change or stall
I have been thinking about changing my gear ratio in my C5 auto from a suckee 2.73 to 3.42. Someone suggested adding a "stall". What is this? What does it cost to buy and install? Is it better than changing gears? What are advantages/disadvantages?

If you are goning to be swapping the gears, you minus well install an after market TC since the entire driveline is removed from the car. Here is a good website that describes some of the questions you are asking.

if you are eager for a higher stall TC, then doing gears at the same time is very dollar smart

A high stall T/C will give you more performance than just gears. Unfortunately you have 2.73 gears so you will also need to swap gears along with the T/C.
It should cost about $300.00-$400.00 to swap the T/C. To swap gears and the T/C figure on $500.00-$600.00.

Not true, you don't have to remove the transmission or the entire driveline to change your diff gears!
Just do it very carefully when lowering the rear cradle and watch the clearence between the firewall and intake manifold.
3.42 with a stock converter will put miles of smiles on your face.
3.42 with a stall converter will put a real hurt on your wallet.
JMHO it's the first change I did to my 98 A4 now with about 40,000 miles on it with a Procharger and still the stock trans.

I look for the least expensive thing to replace and use that for the fuse in the driveline.
Besides 99.9% of my driving is on the street!
