Has anyone experienced shifting issues caused by an issue with the battery? I have a 2018 that after driving for a while in 105+ degree heat begins to only shift between 1st and 4th. Trans Temp only showing 174 at the highest before “issue” begins. Fluid level is good. The only other time I have experienced this was when I had a bad battery on my camper I was towing that was backfeeding and caused the same issue. Disconnected that battery and everything went back to normal. I have had to replace the original battery since and replaced with a Costco Interstate AGM. Now on my second one of those. Any ideas?

I think you have a 66rfe and they had issues with the electrical connections to the solenoids. They also had some recalls in certain years for the same. I had a 2016 with that trans and it was the reason I traded to a 19 as soon as the ZF was available.
I personally hated that transmission.
