Warranty expired while in an out-of-state shop for a month. Ford shipped me the truck, I immediately took it back for a new noise, and now they're saying too bad the warranty expired. Anybody have info for me so I'm knowledgeable on this?

*2020 Ranger Lariat FX4* **December 14, 2023:** While on vacation in Seattle, WA my truck spontaneously shifted into 4L while on I-5 and wouldn't go back to 2H when I pulled over. **December 28, 2023:** bumper to bumper warranty expired **January 19, 2023:** Ford shipped the truck. I picked it up from a dealer in Los Angeles with a brand new transfer case and transfer case motor. Once I drove away onto the highway I started to hear a spinning noise. By the time I realized it, the dealer had closed. **January 20, 2023:** Dropped off the truck at the same Los Angeles Ford service dept. **February 22, 2023:** After a month of delays the service dept tells me the driveshaft is leaking (covered under powertrain) and the driveshaft needs a new bearing (not covered under powertrain). They're refusing to work on the truck until they're given authorization that I'll pay. None of these issues existed before I gave the truck to the Ford dealership in Seattle. Ford Corporate hasn't been super helpful. They're refusing to engage in Lemon Law discussions until the truck is out of service so I'm kind of in a Catch 22. Does anybody have any input at all so I know how to deal with this? Is it possible driving it around in 4L caused the issues? Was it towed improperly? I just need to have some info so I can fight it or know who to go after. I'm usually good at this stuff if I have all the facts I need but I don't know that much about mechanics to fight this.
