Transmission failure out of nowhere!?

Well I got in my Explorer this morning to go to work, engine started fine, but when I put the transmission into drive it never went into gear. R D 3 2 1 all do not engage.

I'm getting two codes:
P0731
P0735

Now the most bizarre part is that it has not shown any symptoms of failure. This is completely out of the blue.

Going out to check fluid levels, anyone else with any ideas?

Fluid level was fine. So I reved the engine slightly higher to get it moving. It moves and the trans appears to shift between all the gears but it is not engaging , then jolts the car forward, and slips once the vehicle is rolling? There is also a whining noise that was not there the night before.

Any thoughts? Took a quick video.

Did you get the codes pulled?
