Hey, I hate to tell ya, but my my Contour acted like that, it turned out the be the Torque Converter had died. Had to get the tranny rebuilt.
My Tour was fine one minute, then, when I stopped for a light, it would not go once the light turned green. Acted like it was in neutral. I finally got it moving a little, and once it got up to 20 mph, everything kicked in, and it was fine. Then it would do it again at the next light. I got the flashing O/D light and CEL. I was too afraid to drive the thing anywhere after that.
I used our truck while a friend changed tranny fluid, that didn't help. My dad even came down from Virginia, checked it out himself, he couldn't figure it out.
So we had AAMCO fix it.
