If your semi truck had no gear box, it would be almost impossible to move your truck from a standstill position and speed it up, especially when towing a trailer. That's the reason why your truck has a transmission system. No matter whether you have a manual or automatic transmission, it serves the same purpose, allowing your engine to run at optimal RPM, while changing the speed of the vehicle. If something goes wrong with your transmission, you may hear a whining, clunking or humming noise, as well as experience gear shifting problems. Fortunately, proper maintenance and quality semi truck transmission parts from TRUCKiD will allow you to avoid such an experience.
