this could be a problem with the trans module. did you lift it yourself?? if you did have a 4wd shop reprogram the shift points. the trans speed is what causes the trans to shift in relation to the engine speed. when you lift it the engine trans want to shift like stock. i dont know if titans ca be programmed for larger tires. its the whole thing about the speedo being 5 mph off. otherwise maybe an electrical issue. i may be wrong just a suggestion
