the O/d light flashed on then off, a few miles later my 06 v6 all wheel drive just coasted to a stop, no noise or anything else. The engine light is on. The trans oil does not smell burnt. The park works but absolutely nothing for the other gears. I drained the tran fluid, 1 gallon came out. Put back in one gallon of new but it is way high on dipstick, the pump seems to not circulate the oil. My car only has 75k on it.
Any ideas as to what to do next?

 

Tow it to a transmission shop for a rebuild or replacement. Plan on spending $3K to $3.5K.

 

Your pump drive shaft has likely quit driving the pump. That means the pump doesn't work any more. It may be possible, I think I've heard elsewhere, to repair the pump externally, but don't bet anything on that. The CD4E pump is at the drivers end of the transmission, which may make it accessible. BUT, I have also read that the driving end in the torque converter may have a too-thin driving plate which can fail, either way, the pump doesn't work. There is a 14"+ long shaft from the center bore of the torque converter that goes all the way to the opposite end of the transmission where the pump is located. It drives a gear to power the pump.
I'd bet it'll have to be at least partially taken apart, more likely pulled for disassembly and repair. Given the cost for R&R, and disassembly, it makes sense to replace seals, O-rings and other wear items when they are accessible on the bench. The actual 'kit' that contains all the seals, and so on, but no 'hard parts', is but a fraction of the total expense. The main cost is labor for the Removal & Replacement along with the disassembly and re-assembly.
Talk to a transmission repair shop you trust. If you don't have one, ask for recommendations from friends and acquaintances. If they have none, at least talk to several for a ballpark estimate. The estimate should state what they intend to do, and what will cost 'extra'. And their warranty conditions. If you do have it rebuilt, make sure you replace all bushings as they seem to be a good source of looseness that makes hydraulic pressures drop, leading to slip, heat & failure.
It may be that the transmission itself doesn't need work, and you'll just have to replace the torque converter. I don't know if the pump plate is replaceable by itself, or the converter has to be cut apart for repair, and then re-welded back together. It is your choice of how much to spend in that case. If you know a general mechanic you trust, you might get by with just swapping converters, but that calls for pulling the transmission for access.
I hope I don't have to learn about this myself.

Nope, it's impossible on a CD4E.
