[Vwdiesel] How could I Grind the Gears Doing This?

[Nate Wall]

Last night I was driving the Jetta TD. We got a little snow, so the road
was coated. I was slowing down doing about 15 mph or so, so I proceded
to downshift from 3rd to 2nd. Just like any other time, given the road
speed. But.... As I was braking, the wheels totally locked up because of
the snow. As I depressed the clutch and downshifted with the wheels
locked, the gears banged (or grinded) quite noticeably and it then went
into 2nd. What happened? Isn't this like shifting w/ the vehicle
stopped, since the wheels locked? Interesting. Its the first time
anything like this has happened. Its almost as if I tried to shift w/out
the clutch.
