Syncros are..............
small gears in the tranny that help you to select gears while shifting. They are made of softer metal than the gears, so that is you screw up a shift royally, you're not beating the hell out of the real gears, you're just losing a little soft metal ring.

The drivetrain is bulletproof.
People are modding these cars to 300 horsepower (twice their stock level) and the trannies are holding up great.
The shifter feel sure sucks if that's what you mean, but the tranny itself is rock solid. Esp. Quattro.
Some weak A4 points: Control arms, cylinder head, wet braking, etc.
Bulletproof stuff: 1.8t bottom end, drivetrain, body integrity.
Everything else falls in between - not great, not bad.

Basic use of syncros...
they match, or syncronize, the speed of the gear you are shifting into to the speed of the engine. They make it so that you don't have to rev match your engine every time you shift. It is not uncommon for them to break on any car if you do a lot of hard shifting up or down at high rpm's (granted, they shouldn't be broken on a 1 year old car unless put under major abuse).

Tranny internals are fine. The synchros go when people abuse the tranny, period.
If you're synchros are gone prematurely, 99% ofthe time it's cause the driver is hamfisted.
You don't have to pound the lever to shift quickly. I can shift like phucking Tinkerbell and still be quicker than someone who just swats at the stick. It's all about accuracy, smoothness, and proper rev matching.

Re: Basic use of syncros...
Love the sig... But I guess that I put my car under alot of abuse. I autox with it. But at the same time I can go 0-60 without letting go of gas pedal or hitting redline. (and go fast)

Just cause you autoX or drive fast doesn't mean you're hurting the tranny.
just make sure you give the tranny the right set of conditions to mate properly before you get into gear.
Do NOT pound the stick into gear if it doesn't want to go naturally.
DO match the gas more carefully and it'll go faster on it's own.
Try this - try cruising to a red light in second, and try to shift into first. Hard as hell = no first gear syncro.
Now try the same thing, but give the car enough gas to let the car get into first easily as you push the stick forward. It'll go smoohtly if you match properly.
What you just demonstrated was what happens when you are doing normal shifting - if you don't properly match revs, and wait for the tranny to be ready to go, you're making the syncros take all the resistance that you proved was there in the first example.
Repetitive abuse like this will cause constant grinds and a tranny that looks like a grenade went off when it's opened up.
