    0411 swapped 7.4L 4L80E 4WD Low Stuck In First

    Truck runs through the gears in 4WD high but not low. Stays in first. Another problem is it shifts in 2WD as I wish and then the TCC locks which is what I want. I let off throttle and it unlocks but will not relock.....??? I will post a tune tomorrow if anyone is interested in helping!

    Thanks!
