Adjusting column linkage

[Jotto82]

Doesn’t always happen but on occasion my truck will fall into reverse from Park. The marker doesn’t line up either. This is something that really sucks with cold weather here in Wisconsin because the motor needs to warm up and I have to sit in the truck the whole time because I’m never sure if it’s going to happen or not. Is there a thread on this that anyone knows of or can explain it. I’ve crawled under the truck and found it but not sure what to adjust. Any help is appreciated as always!
