Q: d4 blinks lost of power high idle

asked by on

my d4 is blingking and sometimes fees like changing gears in low speed , and lost of power too plus my gauge is actinh abnormal

My car has 134000 miles.
My car has an automatic transmission.

This is a transmission code indicating a problem with the transmission. This is most likely why you are experiencing the feeling of shifting gears at a low speed. This light blinking can indicate many different things. I would recommend having an expert use a scan tool to download potential codes from your car which will help pinpoint the cause of the lost power.
