I know I've posted about the tables being mislabled, as well as the 4-5 shift table before. So far for me anyways, all of the LB7 5 speed OS's have the tables reversed. The pattern B tables are labled as 4 low, but are actually tow/haul, and pattern D is labled tow/haul, and is 4 low. Last I seen posted on it was that you had changed them around, and then somebody said it was backwards for them, so you changed it back and left it.
