Connector between tranny and shift linkage?

[Howdy y'all]

I had the transmission serviced at 70k with a flush, fluid, and filter change on my 2004 Suburban. I drove out of the service station and everything was running fine. The next day I got a call from my wife saying the shifter would shift freely, but never engage the transmission. It was towed back to the station. They stated the plastic piece that connected the shift linkage to the tranny was not attached. I am planning on a cross country trip in 3 days and I am nervous this would happen on the road. What is your experience with this "plastic part? Do y'all think they just didn't firmly seat it or do these break rountinely? Should I take some JB Weld for on the side of the road repair? Thanks for any advice.

Sounds like they just did not hook it up correctly after working on it. If you are worried, have another shop take a look at it.

On my 2000 Yukon (4WD), I had to remove the shift linkage bracket to get the pan off. Perhaps when they did that, the linkage was not on correctly and disconnected.

Yes, the shift linkage has to be removed to drop the pan. It takes a pretty good squeeze to get it back on. I'd say whoever put it back on didn't quite get it snapped into place and it worked its way off. Just crawl under and give it a pull, if it comes off easily then it'll have to be fixed. It should take a pretty good tug to get it off by hand. I usually stick a screwdriver or prybar in between the shift cable and linkage on the tranny to get it off, and press it back on with channel lock pliers.
