Now that I thought a little on the sound clip I heard on 9208K,
here's my comments.
No. That's not the only VO that locks up at 2nd. A number do
that. While the VOs are supposed to lock-up at 1st, there are some
ZFs that are flexible enough to do that at 2nd instead.
Now that I think back, those VOs I took that abruptly
"locked-up" early in 1st were actually transitions into 2nd, after
which, the lock-up occurs. Half the time, this fails.
Initially I thought it was the lock-up disengaging because it
engaged early.....but now I reckon its actually 2nd to 1st when the
bus starts shuddering. The steeper than expected drop in rpm
for such buses at that stage should be the biggest indication
of 1st to 2nd rather than lock-up.
