is a o/d lockout possible?

[bmiller04107]

in my 2001 continental in gear position 3, under full throttle it shifts at like 85-90 at about 5000 rpm into o/d, is there a way to install a o/d lockout like in a markviii so I can fully run through the gear?

just put it in d until your ready to drop it into od
