On the A-type OD, there is an accumulator that can hold pressure even
when the solenoid is not powered, sometimes for days.

The Sprag (or one-way) clutch ensures that the OD input shaft cannot
turn further clockwise (looking at the front of the unit) than the
output shaft.  This means the output shaft also cannot turn further CCW
than the input shaft.  However, in reverse OD, the OD gears force the
output shaft to turn further CCW than the input shaft.  Something's got
to give ...
