Overdrive Off Indicator
The overdrive off indicator light
This light tells you that the Transmission Control
Switch (TCS) has been pushed. When the light is
on, the transmission will not shift into overdrive.
Depressing the button will return the vehicle to
“overdrive on” mode. The transmission will be
in the “overdrive on” mode when the vehicle is
started even if the O/D OFF mode was selected
when the vehicle was last shut off.
NOTE: If the light does not come on when the
TCS is depressed or if the light flashes
when you are driving, have your
vehicle serviced at the first
opportunity. If this condition persists,
damage could occur to the

It is most likely the mlps is bad on your trans its a pretty common problem on cougars. Go to a shop and have them pull your codes to be sure, since there is no warning light for your trans they use the o/d off light as a way of saying hey somethings wrong!
