I just made It to 960 miles on my 2020 JL and Check engine came on, only revved, and told me to go into park while the D flashed at me.
dropped It off at the dealer for repair, but trying to see if this is common or whats up?
For those following, did several flashes.
One to transmission, one to clutch and one unrelated. The clip holding the trans cooler lines came out of cooler at radiator.
Thus over heating the transmission and then loosing the fluid. Assured no damage.
