That doesn't make sense, the anti-drainback valve is a separate part to the cooler return line filter. It screws into the case near the cooler filter but they are not the same thing. The anti-drainback valve ensures the pump and internals stays charged with fluid.

This link should take you to a parts diagram that shows it in the same area as the two trans filters. It is labeled as #17: http://www.factorychryslerparts.com/sho ... ct=4289276

No or I'm pretty sure no - see my post at viewtopic.php?f=5&t=76498

PN 04799681 (ca. $10) is not part of either filter although it's located in the same general area, just forward of one of the filters if my vague memory of a pic I cannot find is correct (parts diagram is no special help). Whether or not it has any relation to the drain back problem I do not know but it's cheap to replace.

If you look at the pics in my sig you'll see 2 trans pictures. The part # listed in this post is the gold nut valve sticking down between the 2 filters. This 'flow control valve ' opens if the cooler or filter is restriced andto bypasses
fluid.

So what happens if this "FCV" sticks? If it sticks open, does the TC drain out while sitting for several hours? What bad things happen if it sticks closed?

Bought the flow control valve - only 7 bucks !
