Now, engagement-of-reverse is already detected so as to light a back-up
light. Why not use it via a relay of some sort to dis-able the OD? That
way you could have OD in 2nd (and 1st too, if you were so inclined).
On the early TR2's, the OD was allowed to engage only in top gear,
because the actuating pistons weren't large enough to keep it from
slipping a little if you, um, accelerated with vigor in the lower
gears. Eventually this would burn it up. When people realised that the
O/D was useful in the lower gears too, they redesigned both the O/D
and the lockout switches to let it work in second and third. It still
couldn't handle the torque of first, though. Might be true of a Spit
O/D, too, if it originally worked only on the top gears.
