Hi, thanks for writing in. If I am understanding your question correctly, it sounds like you may be having a shifting problem. This may be related to many different things such as a faulty TCM (transmission control module), low transmission fluid, failing valve body or a bad shift control solenoid. Any or all of these may cause shifting problems. Without additional details as to specifically what the truck is doing when shifting, this may be difficult to diagnose. I would recommend having an expert from YourMechanic come to your home or office to confirm a diagnosis on the issue and make or suggest the necessary repairs or replacements.
