Hello: I seem to have discovered a way to pop a code that might be an issue with the tranny. I have had my 2021 Wrangler Unlimited High Altitude 4xe for about two weeks now. I've been experimenting with the different power settings and recharge modes because I was hoping to give this one to my wife since she has a longer commute than me. Had my vehicle on ESave mode with max recharge (Bat was at 4%). Was letting the vehicle coast to the red light and applied the brake at a low speed to stop fully and the break made a big clunk stopped fast and the D indicator light started flashing. When the light changed I could not move until I shifted into neutral and back into drive. I was able to recreate the error 1x after that. I stopped because I didn't want to break it. Any suggestions?
