I’m currently driving my Brother’s 2018 Sahara JK while he is recovering from heart surgery. Yesterday I was getting up to speed on the highway when it started slowing down while I was still accelerating. A red lightening bolt appeared just above the temperature gauge. I pulled over, put it in park, waited a few minutes and started going again. The lightening bolt went out and everything was fine again. Any ideas what might be happening? Do I need to have the transmission filters replaced? That’s what came to mind first.
