Yes, quite probable, I'd say.

If you like electrical tinkering more than dropping of gearboxes, you
could always wire up a normally closed relay connected to the reverse
lamp circuit, so that overdrive is disabled whenever reverse gear is
engaged.
This is a hack, though, because it still allows OD operation on 1st gear,
where the torque on the outgoing axle really is too high for the OD, in
addition to the RPM being to low for proper hydraulic pressure.
