This is the “Street” series of our Aisin Seiki AS68RC rebuild kit. This transmission is known for countless unique and difficult to understand problems that have kept it far away from the aftermarket for years.
To go into greater detail, the factory AS68RC transmission is known for rancid pump and valve body issues that often leave cores damaged beyond worth. It is extremely common that cores that are sent in will be damaged beyond their core value because the pumps have been obliterated.
Beyond this, once the pumps are damaged, they must be purchased in conjunction with a valve body as they are hydromechanically calibrated to one another, and cost $4,000-$5,000 brand new, hence why these units are often exceptionally expensive builds.
Many people think because of this that the 68RFE would have been a superior choice. This is not entirely true; we’ve done a Transmissions 101 addressing all of the common questions. You can read more here:

Fortunately, we have gone back to the drawing board in the interest of creating a product where the priorities of power capability, durability and performance were all the largest priorities. The result was our exciting and powerful “Street” Aisin Seiki AS68RC 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 Street Aisin Seiki AS68RC Transmission here:

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.
