This is possible but only in Drive but not D2, D1. It's possible that D2, D1 in the gear selector switch is not tied to the computer.
I live up a nice, slow hill. As I come down the hill half a mile later I start the car with the throttle closed. At this moment the rpm shoots up then the injectors comes on and stays on unless you speed up and close the throttle. This is a small town. So, if you skid into a ditch, everybody will try to help and hardly writes citations.
Yes, the injectors stay off if you go from third to fourth. It doesn't work the other way around. The programmer never thought about high gas prices and drivers like us.
The best way is to avoid shifting to D2 but instead keep it on Drive and let the modern computerized transmission downshifts for you.
