Hey all, I went off-roading in my new 4xe today for the first time. I have done these trails in my old 2018 JLU, but hadn't yet in the 4xe. The first trail I hit starts with a slower, rocky climb. I was in 4HA, and my trans temp spiked to about 290-295F before the car threw itself into "limp mode" and automatically into park once I stopped. Throughout the day, I found that 4HA and 4HP kept the engine RPM to about 1500, and the trans temp would spike. But if I went into 4L, the engine would hover somewhere between 2-3K RPM, and the trans temp would lower. This only happened when going up hills; it did not matter if I went up it quickly or if I was crawling, but crawling up the hills did cause the temperature to go up quicker. A few times when it did this I started to smell the transmission, and heard a weird noise at one point, but instantly kicked it into neutral or park when that happened.
My main thought is maybe trans fluid is low, I will check that when it all cools down, but I was wondering if anyone else has had this problem. I also recognise my old Jeep wasn't a 4xe, so it's not apples to apples, but I can't imagine it is "normal" to spike the trans temp to nearly 300F
Update: I read the forum below, but I wasn't sure if anyone else had any tips other than kicking it into 4L. I am also a bit concerned because it seems other peoples warnings are kicking on at 220, while mine didn't kick on until 280/290.
