Tcase shift linkage keeps falling off

As the title says, the linkage keeps falling off. My truck has the floor shift for the transfer case. About a year ago I went to put it into 4wd and the shifter just had free play. So I go look under there and the rod is gone, the rod the connects the shift handle to the lever on the transfer case.

I had to climb under the truck for 6 months to put it into 4wd because I could not find a replacement anywhere. Every junk yard within 100 miles from me all had trucks with push button shift. I just couldn't believe that I cannot find one truck with manual shift.
Finally I got sick of it, and looked for 1500 series trucks with manual shift. Sure enough, there was one local. I paid the guy $20 for this stupid linkage rod. I go to put it in, and its too short!!! I forgot the 4L60E is shorter than the 4L80E so I had to chop the rod and make it longer. That wasn't all that hard.
Well guess what, it fell off again. Except this time I managed to find it.
There seems to be clips inside the plastic ends of this thing that are looking kind of worn. I have looked high and low, everywhere from Napa, to Rockauto to google. I cannot find any hints that the manual shift linkage even exists!

Does anyone know where to find replacement ends for the manual shift transfer case linkage?? I cant believe I am the only one on the face of the planet with this issue.

I have pursued that avenue as well, and they don't have anything. Its hard to believe that a wear item on the truck cant be replaced and that when the plastic ends wear out, your left with climbing under the truck.

The end links are the same as what you'd see on lift gate struts- metal ends that pinch a ball joint.
I would either take some pliers and pinch those two metal flaps together closer to retain the ball end they connect onto OR look up the upgraded transfer case linkage rod, which does not have those type of ends- they are big blocks of nylon with a similar joint to grip the ball-end.

There's multiple part numbers I found for 2004 2500:
https://www.gmpartsgiant.com/parts-...arts-list/2004-chevrolet-silverado-2500-hd-4wd/transfer-case-shift-control.html

Scroll down to "ROD, Transfer case shift external shift control"
There four different parts, you'll have to check against your RPO codes.
Each are about $25.

Thanks for that link CT2500HD,
That led me to finally be able to find someone who sells these rods.
The descriptions are a joke but luckily they indicate RPO codes for each rod.
I was able to decipher which one goes to 4l60E, NV4500, Allison 1000 and 4L80E models and I ordered the one for RPO code MT1, NP2, HVY.
Looks like it may be the updated one.
Those part numbers all cross over to GMpartsdirect but on that site there is absolutely no description what so ever.

Thanks

can you not fabricate a better linage with attachment points?

Or upgrade to the electronic version!
Problem is getting the attachment points....

I would think that switching to the electronic version would be very cumbersome and expensive. I would need all associated wiring, electronic buttons, the NP263 transfer case as the NP261 is otherwise identical but manual shift, and I don't know what kind of reprogramming the computer might or might not need.
I would rather climb under the truck for the next 4 years(time I anticipate ownership) than spend the couple thousand it would take.

One of the reasons why I got the WT trim was for the manual transfer case shifter (along with all sorts of other features I did NOT want that would just break in time). How many hundred threads are there on this forum about electrically-actuated transfer case shifters malfunctioning? Why do we think Jeep still uses only manually-shifted transfer cases in all their Wranglers?

Its still one less thing to break.
The actuator on the front isn't all that failure prone and if it does, its easy to swap out.
