I have not but have looked up how to do it and posted instructions from my shop manual on here before.
If memory serves, the valve body has to come out and maybe the tailshaft as well. Sometimes people bend them while doing transmission work and they can be bent back to working again.
Did you first check to see if it was the cable or connection on the side of the transmission?

No I didn't check. I'm assuming the worst right now. I'll get under the truck later and verify that it's in the correct position. Do you have a link on your post about it?

No link, it wasn't that detailed. To do the work you ought to purchase a subscription to the shop manual from places like Mitchell or AllDataDIY.
As @swathdiver said, the actuator rod is probably damaged and can be removed/replaced without pulling the trans, but you may to need to pull the valve body to get access to one of the roll pins.
There was an update around 2008 to a stronger rod, so I would upgrade if necessary. The rivet on the end also gets damaged from being forced into park, so even with the updated rod you made need to replace it if it is damaged. But once you drop the pan it is visible.

This rivet can be replaced easily as well?

You might have enough to drop your Y pipe to get your pan to clear the exhaust. You might get luck and it will just clear with a little persuading of the pipe.
I have the detent spring removed here for visibility, so you can see the parking pawl engagement rod attached to the shift lever. You need remove the valve body, so that you can access the roll pins on the shifter shaft. One pin holds the shaft in the case and the other holds the internal arm to the shaft. Technically the 'pawl' itself should be fine, but the rod from the arm back to the pawl engagement is what is likely bad.
if yours is AWD then there is no park, the front and rear wheels bind together which is why it will roll away on you if you are on any kind of incline and jack either end up off the ground.
no park on a gm AWD, go ahead and try jacking it up and see what happens, mine rolled out the driveway....... until then I was not a believer
That is a pretty far out statement. Anyone who jacks up a vehicle without chocking the wheels on an incline or using some other method to restrain the vehicle should not be jacking up vehicles. Anyone who jacks up the drive wheels on a car on an incline expecting transmission park to keep the vehicle in place should not be working on cars.
Just to further clarify, if you have a RWD or AWD vehicle in 'park' on an incline of say 5 degrees, and you jack up the rear end (being one of the either ends in your statement) with a wheeled jack, it is likely going to roll downhill. It is also very dangerous and should not be attempted.
However, that doesn't mean the transmission 'park' feature is missing or not working. It also doesn't mean that AWD doesn't have the same 'park' feature.
lol, NO PARK ON GM AWD SUV'S, AWD vehicles have no park instead it binds front & rear axles. still shows "park" in the cluster like normal it just doesn't park in the traditional sense. done with the matter, I was only posting this info for the OP in case they were not aware and thought perhaps they had lost park.
on a separate note I have broken the parking pawl on a non awd gm suv before among many other things
if you jack up your 2wd or 4wd gm suv (with an actual parking function) and it rolls away on the rear wheels then ya you have a problem, normally it should not budge, however a AWD gm suv will roll away, it might not so much if the parking brake is set but the parking brake does not hold nearly as much as parking would on a non awd.
also if you put a gm awd in park and lift up all 4 wheels front and rear will turn together in opposing directions NO PARK function.
but don't believe me, go try it for yourself........ i suggest you not stand in the direction of travel or just let natural selection take over.

Fair enough Wes, challenge accepted.
I understand, I didn't believe it either I think it must have something to do with the transfer case, not really any information about it out there
but if you lift those front wheels off the ground it will walk away
I can confirm that the truck will still roll with only the front wheels off the ground.
That doesn't mean that the 6L80 doesn't have a parking pawl. The parking pawl is just a device in the transmission to lock the output shaft to the case.
