Has anyone has similar problem (Auto Gear)? It doesn't happen every time, you won't know when it will happen ! During normal driving, look like a change of gear but a shake then engine light turned on and the gear light is blinking ! I have to stop the car turn it off and start again in order to make it normal again. I have already changed the knock Sensor & Oil filler, it still happen.
Have you tried scanning the ecu with an OBD2 reader? If a check engine light is on there should be a code stored.
