The only thing I have seen effect all gears as you are mentioning is if the
clutch/throw out bearing was not functioning correctly.  This could be the
master/slave/bearing/shift arm that controls the bearing, and pressure
plate.  If it is anything internal it usually lets you know very loudly and
clearly that it is internal and not just at shifting.  Also will normally
kick out of gear.
