[A4] A4 clutchless shifting

[Ed Kellock]

I would add that pulling it out of gear is much easier when there is no load
on the transmission, i.e. just as you come off the throttle and just before
engine braking occurs.  If you put very light pressure on the shifter when
you come off throttle you'll discover where this point is for your
particular vehicle.
