When I run the car cold (as it needs to be), and I shift into 2nd, it get an audible grind (but the gear catches fine). As the car warms up, the sound disappears completely on 2nd gear shift. Occasionally, I'll feel the gears grind when I shift into 3rd (hot or cold engine). Is it my clutch? Or my transmission? Would it need to be rebuilt, or can this be fixed by changing the tranny fluid?

2000 Audi TT Quattro Question: Grinding when shifting into 2nd, 3rd
Change the fluid first. Amsoil has some good syncro-mesh that works well. I use it in the M3 race car.

We've seen this before, it's most likly the #1 and #2 syncros. The problem is, they are brass and after a while they become more egg shape then round. You can try to adjust, but 90% of the time you have to replace the syncros. I hope this helps. Take care.
