    I have a 2012 regular cab 4x4 with the auto. Trying to figure out what gears I have. The door jamb has the A02A axle ratio code. I have seen conflicting ratios for this code. Some say 3.58 and some say 4.10.

    Take out the drain plug, mark the ring gear with a paint pen and turn the pinion and count how many times it takes till the paint mark comes back around. You have 4.10s but thats a way to verify. I am fairly sure only the 5 lug trucks had the 3.58s w/ the auto

    I agree. I haven’t seen a 4x4 w/2.7 engine that wasn’t 4.10.

    I’d refer to this chart, for the 2nd Gen trucks.
    It’s been fairly accurate. It indicates that you have 8”/4.10/Open
