so today my 2019 Pro 4x did something funny and not sure if I should worry about it. I was in 4 low with rear locker engaged but when I went to turn it off and put back into 2hi, the truck started beeping I would not go into gear. If I went to park, I would hear a grinding noise. Reverse or any of the forward gears did nothing and truck would not move. Anyone encounter this? Should I be worred?
