Competition Allison Rebuild Kit w/ Torque Converter (1200HP)

Next Gen Diesel

Introduction:

     This is the “Competition” series of our Allison rebuild kit lineup. The Allison 1000 and 2000 series transmission is easily one of the most reliable and trustworthy transmissions that currently graces the diesel truck world. However, as with all great mechanical inventions, it is not invincible. It is a promising source of valve seizure, electronic failures and stator failure inside the torque converter, to say the very least.

     Fortunately, we have gone back to the drawing board in the interest of creating a product where the priorities of longevity, power capability and usability were all the largest priorities. The result was our exciting and responsive “Competition” Allison rebuild kit.

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 Competition Allison Transmission here:

  • Daily Driving
  • Towing/Hot-Shotting
  • Stock to High Power Increases
  • Long-Lasting Clutch Materials
  • Freeway Pulls/Boost Launches
  • Very Firm but Predictable Shifts

About Next Gen Diesel 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, 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, 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, this is no more.
