Flashing OD light is usually bad news for the ATX. There is a position sensor on top of the tranny under the battery that I've heard causes some similar problems. Might want to check the level and condition of the tranny fluid just to be sure. You could try Lucas AT fluid conditioner to see if it helps at all. $1500C seams cheap for any serious transmission work as it usually means pulling the tranny. I wonder what they are including in the 'transmision job' ??
