My Supra won't slide into overdrive on the freeway. Cellinoid? Fuse? Lighted message on the dash reads "O/D OFF" Help?

well let is know what year you have, turbo or na, it might help some of the members who might have had this problem before in the same vehicle your talking of.

your button that allows overdrive might be broken...mine popped off and my overdrive wouldnt engage

is the button on your shifter pushed in?

can you push it and does it feel normal, does it switch in and out?
