Has it felt like your 10R140 transmission doesn't shift like it used to? While the 10R140s haven't been around as much as other transmissions, if you are hauling heavy loads long distances it can create heavier wear and overheating which can result in clutch malfunction and fluid breakdown. The 10R140 does have some of its weak points as well that can result in valve body issues and hard shifting which start to show up the more miles you put on it.
