Um, all you have to do is switch off the overdrive to prevent it being
actuated in reverse. Hopefully all users are taking this precaution as a
matter of habit. To be precise, there is no "reverse" lockout, as such -- it
is an "all gears except 3rd & 4th" or "all gears except 4th" lockout
(depending on year).
If the OD switch is in the off position, and the OD is in fact engaged in
reverse, then the damage has already been done.
