From teardown to testing, National Trans is about quality. It’s how we think about each part of our process, even down to the smallest custom bushing. When remanufacturing our transmissions and transfer cases, we exceed OE specifications to make our products more powerful, reliable, and efficient. Product Features: • Every transmission includes a fully remanufactured and improved torque converter that has been tested for leaks, lock-up, concentricity, and balance to eliminate the possibilities of front seal leaks, premature bushing wear, and vibration. • All dynamometer testing is conducted with our proprietary testing program for at least 30 minutes. • During dynamometer testing, transmissions are cold, hot, load, and road tested using our fully synthetic transmission fluid and filtration system. • The fully remanufactured valve body with complete system correction and recalibration kit is tested independently in addition to the fully assembled transmission dynamometer test. • All wear-prone valves in the completely remanufactured valve body are restored to stringent specifications and vacuum tested to verify proper function. • Build specifications are checked by four different specialized technicians during the remanufacturing process to verify the correct application. • Each no-hassle warranty is attached to the vehicle VIN and transferable with ownership, which means no paperwork or registration required.
