05 Sierra 1500 ABS light

[lisa Williams]

05 GMC Sierra 1500 throws code C0055 for rear sensor or something like that which I've changed 4xs plus a new ECM. The issue is: abs..brake light..check engine light will all come on...speed odometer goes nuts...and transmission won't shift. Thing is....it doesn't do it all the time. It goes months and don't do it...then it can do it every day for a week. Trip it off with our computer thing or sometime we have to take battery cable off. Replaced the rear speed sensor...both front tire sensors...new ECM..some other things....but still does it. Can anyone please help! My email is [email protected] if u want to respond directly. Ty
