Overdrive activation and automatic transmission hit
Daewoo Lanos 1998 105000 miles
When setting the Reverse or Drive, the automatic transmission hits strongly. Even more, when driving and activating the low beam lamps and sometimes when turning the air conditioning on, the Overdrive is activated and the speedometer needle drives crazy. After a while, it normalizes and the Overdrive is deactivated. But, occasionally, this does not happen alone and I need to turn off the vehicle so that everything comes back to normal. What might be happening?

You have an electric problem, so I recommend you to check the connection that leads to the automatic transmission. Check properly the ground wires and also that the right voltage is reaching the computer. You will need to scan your vehicle to determine that, and the voltage should be 12V; if it is less, that is when the failure you mentioned appears.

Thanks for your answer, ned. Finally, the problem was the TPS sensor. Thanks.
