My thoughts =E2=80=A6

The clutch is out. It was not stated but I will assume the engine is =
running. If the assumption is not correct then any thoughts that this =
whole process is a =E2=80=98good thing=E2=80=99 should not be =
entertained.

Given that the clutch is out and the engine is running then the input =
shaft is turning.

Given that the input shaft is turning then the counter-shaft is turning =
=E2=80=A6 at least slowly.

Given that the center-shaft is turning then the gears that float on the =
output shaft are turning and getting some lubrication picked up from the =
counter-shaft. Yes, they are turning at a different speed than the =
output shaft, but that is what those not engaged via the =
synchronizer\gear selector hub to the output shaft at any given time do =
for most of their lives anyway.

Given that the output shaft is turning (the driveshaft has not been =
disconnected) then everything is turning, which is exactly whey they do =
when it is in gear and rolling.

IMHO =E2=80=A6 no harm to the transmission. By the same token, no =
anti-harm (i.e. no advantage\saving) to the transmission, but no harm.

As mentioned, the brakes may want to file a (rational and reasonable) =
complaint, but the transmission would be fine with it =E2=80=A6 but very =
likely be fine with it either way.=20
