I've always blipped the throttle when I disengage the O/D, just like any
other downshift (except I just lightly tap
the clutch pedal). I never thought of it before, but this has the added
benefit of making sure the O/D is disengaged
before coming to a stop (and maybe shifting into reverse). However, I gotta
think the O/D would disengage anyway when
the RPMs drop to where the pump can no longer keep the O/D clutch disengaged.
The exception is when you're following a slow vehicle at part-throttle, throw
the O/D switch to off when you get a
chance to pass, then hit the throttle to get a 'kickdown' when you punch it.
Also, I bought a new, spare solenoid years ago so, obviously, the one that's
installed will never fail.
