What is called the "forward" clutch isn't the front most one as mounted in the trans, that would be the high,/reverse. The "forward" clutch which is engaged in all forward driving gears is actually the rearward mounted one in position within the case. There are 2 clutch packs in that overdrive unit, I believe one is engaged all the time you're moving forward as well. I know that if one of the clutch paying the OD is bad you won't have reverse.
