Why is the light blinking on my Ford PowerStroke?
In April I towed a 34′ trailer to Talladega and noticed the light blinking. No towing issues at all.

Last night on the way to a dinner, it popped right out of OD and would not pull in any gear (even reverse).

What causes a flashing OD light on an E4OD?
Some vehicles use the ck engine light but the e4od’s and 4r100’s have a dedicated light for trans problems. The flashing od light. There is one exception, the wires go through the shifter and sometimes short out and cause the light to flicker. If it’s a code, it will be a steady blink, not a flicker.
