I have a 2016 Ram promaster city with the 9 ZF9 speed trans. Driving on the highway, as soon as it hits 8th gear, transmission light and engine light comes on and it sets a p0887 code. Trans goes into limp in mode until I come to a stop and put it into neutral or park. Then it's fine again until I hit 8th gear again.
