Our daughter's truck suddenly developed this issue last week. The history was:
- Tuesday the 11th I rode in the truck with her & noticed a slight shudder pulling away from stops.
- The truck stayed in its parking spot(on a steep hill) from then until Friday the 14th. When she started it, it wouldn't shift out of park. When she released the parking brake it started rolling backwards down hill.
- She popped the center console cover off & was able to get it out of park, but it still just rolls backwards freely in any gear, after she lets off the brake.
I'm heading over Sunday to take a look. I'm wondering if something might have happened to the shift linkage?
Converter failure is my guess and it's as common as breathing.

Damn, I was afraid of that. At least I know a local Ford transmission guy.
Well if not a converter I put money on the pump ain't pumping. Since it's a '10, that should be a 6r80.... so yea a pump.
Investigate the doodad that connects the valve body to the pump output. If it's the zf derived one, they crack deliver air instead of fluid.
I forget the specifics, but it's a big thing.
Edit: search transmission valve body seal. Found one on Amazon. They split.
Thanks guys! I'll take a peek to make sure it's nothing simple, but it sounds like it'll be getting towed to the shop.
I just checked out the truck. It seems the shift cable is broken internally, and it must be stuck in some gear other than park.
I'm guessing it likely failed due to the steep hill they have to park on.
Here's their parking situation.
I've noticed that in a lot of autotragics if you let the park pawl take most of the parking load instead of the handbrake, it can take a lot of force to get back out of park. Years of that could be hard on the cable. So I try to park slushbox cars by engaging the handbrake first, letting off the brake pedal to ensure the handbrake is holding it, and then putting it in Park.
In reply to GameboyRMH :
Good point. I know they use the parking brake, but I didn't think to ask their order of operation.
Ford does, and always has, built some crap shifter mechanisms.
As to the parking brake, I often repair rear brakes after a new owner or driver uses the parking brake for the first time since the vehicle arrived in Saskatchewan.
Flat, you know.
In reply to Streetwiseguy :
Have you seen the thing they do now on the F150, where the lever is just a switch?
Shut the vehicle off in gear and the shifter will move itself to Park.
I thought this was just the console hideaway shifter, but to column shifters do it too. I still have to upload that video.
In reply to Pete. (l33t FS) :
I figured that out as I opened thr door on one to drive onto my 4 post hoist.
Weird to watch.
