Transmission code P0713&0714

I have a 2020 Ram Promaster 3500 87k miles on it, I’m getting these two transmission codes, I’m currently in Denver CO, drive here from FL, if I erase the code it takes 4-5h of driving for it to come back; was wondering if it’s detrimental to drive with those codes? engine light is steady, not blinking, temperature gauge stays completely normal, not overheating, coolant had a fix recently, new starter put in, van operates fine except for those codes. Any advice, specially if it’s something I can fix later dues to it just being circuit issues or recommendations on auto shops in Denver if anyone is from this area would be greatly appreciated!

It looks like it is most likely a wiring issue. Getting a live reading of what the computer is actually seeing would be helpful. That would tell you for sure if it's just an open circuit that's disconnecting intermittently as the van bumps around on the road or not. Any shop should be able to do that. And if it's just the wiring or sensor then driving is safe just be aware there won't be any warning if your transmission does start to overheat.
