Flashing then Disappearing od light.
My mom Explorer overdrive light started blinking but then it
stopped all together then later started blinking again. Does
that mean the Transmission is about shot?
OD light flashing indicates a problem with the transmission. The problem could be a transmission mechanical, hydraulic or electrical in nature. Overfilling can cause the fluid to foam and foam in the fluid can cause all kinds of symptoms. Explorers have had transmission issues over the years.
