Xtreme Tow® 6R140 Rebuild Kit w/ Torque Converter (600HP)

Next Gen Drivetrain, Inc.


     This is the Xtreme Tow® series of our 6R140 transmission rebuild kit lineup. The 6R140 was introduced by Ford for the 2011 model year as a successor to the weaker 5R110 transmission. The advent of the 6.7L Power Stroke in the F-Series Super Duty pickup trucks left them forced to design another drivetrain alternative for the newfound power. The product was the often durable but still deeply flawed 6R140 transmission.

     Fortunately, we have gone back to the drawing board in the interest of creating a product where the priorities of longevity, durability and practical use were all equal. The result was our responsive and versatile Xtreme Tow® 6R140 Transmission, now available in rebuild kit format.

Note: This is a rebuild kit, not a complete transmission. If you would like a complete transmission with our 2 Year / Unlimited Mile warranty, see our durable Xtreme Tow® 6R140 Transmission here:

Why Choose an Xtreme Tow® Series Transmission?

          Xtreme Tow® Series transmissions are a unique series of transmissions developed by Next Gen Drivetrain™, specifically for our truck and SUV customers seeking the ultimate work-horse. These transmissions generally feature upgraded pumps, valve bodies, torque converters, drums and friction materials whilst also consisting of a complete and total remanufacturing in excess of all OEM specifications.

       Xtreme Tow® Series transmissions shift crisp but modestly, operate at comfortably low temperatures and are designed to optimize for longevity, low cost of lifetime maintenance and direct OEM compatibility while also capacitating the added power of potential modifications that are common in the working-vehicle community.

     You can find Xtreme Tow® Series transmissions in everything from tow-trucks, to over-achieving daily drivers to modestly upgraded family trucks. Its low cost of maintenance and tremendous durability make them an attractive option for the majority of people looking for a mid level transmission with top shelf reliability.

     If that isn’t attractive enough, these transmissions feature a 2 year, unlimited mile warranty. If you’re looking for a maxed-out reliability build, short of unnecessary racing parts that are not relevant to your application, the Xtreme Tow® Series transmission is the pristine option for you.

Why Choose Next Gen Drivetrain, Inc.?

     Next Gen Drivetrain, Inc. is a Veteran Owned and Operated company in gorgeous San Diego, California that specializes in engineering, developing and manufacturing the height of automotive transmission technology. Unlike most transmission companies that simply buy often foreign-made parts from their supplier, rebuild a transmission and sell it to you at an upcharge, Next Gen Drivetrain, Inc. is not a transmission shop or simple transmission rebuilding facility. We are an engineering and manufacturing firm specializing in automotive transmission technology, ranging from exotic imports to muscle cars to diesel trucks.

     We’ve invented dozens and dozens of different unique transmission parts from nothing that are exclusive to Next Gen Drivetrain™, not to mention developing over 100 different custom transmission and torque converter build sheets. We do not sell our popular inventions such as our Project Carbon® valve body upgrade kits to other large transmission companies, making Next Gen Drivetrain™ products truly unique to Next Gen Drivetrain™. Next Gen Drivetrain™ parts are proprietarily engineered in-house and manufactured right here in San Diego, California.

     Further, everything we develop is designed to be the highest quality and best functioning component first, with all other metrics secondary. For example, things made of Aluminum will often be Steel or Tungsten at Next Gen Drivetrain™. Things that are cast at other companies will often be CNC Machined at Next Gen Drivetrain™, and so on. When purchasing a Next Gen Drivetrain™, you can be assured that you’ve chosen the most premium option available, far more than some basic updates and a colorful painted exterior.

     We highly encourage you to compare our build sheets to any similarly priced product by a so-called “competitors” as you will see Next Gen Drivetrain™ products have no true equivalent, featuring the most extensive set of deliverables at their respective costs. Best of all, we are always just a phone call away, and happy to discuss your personal needs at length to ensure you’ll love your new product.

    About Next Gen Drivetrain™ Transmission Rebuild Kits:

         There are two main problems that most will come across when buying a rebuild kit for their transmission. The first problem, is the kit simply not having the parts needed to finish the job. Many rebuild kits come with gaskets and seals, a friction module and a shift kit. Although these are all justifiable purchases, they leave someone committed to “doing it right” with much to be desired. At Next Gen Drivetrain™, this problem is simply nonexistent. We are proud to include every last component necessary to not only complete the job, but complete it properly and not have to purchase additional parts like electronics or bushings elsewhere.

         Secondly, it is just short of a standard for rebuild kits to possess different parts than what is used in the actual product. (i.e. lower quality clutches than what are used in the manufactured product) At Next Gen Drivetrain™, we simply disagree. Our high performance rebuild kits are comprised of the exact same parts that we use in our own complete transmission builds, down to the clutch material. It may be a common practice for the rebuild kit to hail in comparison to the real deal, but at Next Gen Drivetrain™, this is no more.
