Anyone replaced their transmission drainback valve?

I believe the part number is 4799 681. They call it "Valve, flow control" in the parts CD.

Exact location would be appreciated.

Thanks,

It's part of the spin on cooler filter.Aftermarket version have issues and the OE filters are re-designed to fix any issues with aftermarket and older OE spin on cooler filters.

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.

Can you post a picture, diagram, etc? I thought it was the black thing on top of the spin on filter, and it came with the new filter when purchased from Mopar? I guess I was mistaken here?

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

Thanks! That was precisely what I was looking for. I think that does come with the spin on filter...

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.

It's that black piece on top of the cooler filter,comes with the filter.

I did an image search and came up with the following pictures showing the underside of the transmission with the filters and without. I think the drainback valve in question is just left of the spin on filter in the picture, but please correct me if I am wrong:

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.

Correct,and the anti-drainback valve is part of the cooler filter.

I replaced mine in Feruary of this year.
Mopar #4799681 Transmission Flow Control Valve. About a $7.00 part
Just unscrew it and screw in the new one.

Then that is much different from an ADBV. The ADBV is built into the spin on filter. That is the rubber flap you see behind the outer holes of the filter.

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?

Just effects the cooler part of the trans and will not drain the TC.Will drain the cooler and lines that can foam the fluid for a few seconds before the lines fill again if stuck open,no effect if stuck closed with a good spin on cooler filter in place.

So this bolt is not the Anti Drain Back Valve (ADBV)? But it IS the Valve, Flow Control?

I have a WIX filter kit in the garage and of course nothing came with THAT spin on filter.

Same question? I guess I should go to the stealership and buy the flow control valve part # 04799681. Right?!

06PeakBagger · **Posted:** Fri Sep 27, 2013 7:58 pm

Bought the flow control valve - only 7 bucks !
