I recently have had problems with my 99 Sables transmission. The O/D started flashing and I lost drive for a while. The filter and fluid were changed, but I am still having problems. I have to manually shift when I first start off..then stop and go shifts fine. What would cause this? I have heard that if the O/D is flashing that it means an internal problem...but with what?
