i recently changed the breaks and breaks sensors and none of the light went off.

 

do anyone know how can i repair my seep gauge.

It sounds as if you have a wheel speed sensor problem. This is why your esp/abs lights are on and your speedometer is inoperative. That being said, I have never seen a faulty wheel speed sensor cause the speedometer to malfunction. Is your odometer still working? You need to pull codes to see why those lights are on and while your at it, check the codes in your TCM (transmission control unit). Your shifting issue is probably not related to your inop speedo, but you won't be able to tell unitll you check codes. Possibly you may need a new shift plate in your transmission (which involves removing the valve body).

 

yes i replaced the shift plate. still same problem. can any one tell me how to reset the codes. i did the battery trick and the break peddle trick as well
