I have a 2003 GMC Sierra 5.3L extended cab auto trans. I swapped out the factory 3.73 rear end gears for 4.30's. I changed tires from 29 and change to 32. I programmed for the gear and tire change. Under WOT the traction control was kicking in and the abs light is on. from reading online it seems the abs front and speeds are different causing the issue. Could use some help on this please.
