I’ve seen them fail on the Ram trucks you speak of but on the hellcats I haven’t had one with the issue
Brian Carter’s car had tried to eliminate it and he ran into a converter charge issue and the car would not shift 1-2 under full throttle at the track , he went in a ghost chase trying to figure out what the issue was and finally he reinstalled it and the car went to shifting again,I believe his is a 19 model maybe the later models are different as I know earlier models from people that have removed them haven’t had that issue, me personally I’m ok with it being in the vehicle because I’ve never had an issue and the trans has broken 4 e drums but has never showed an issue with over temps
