Street Aisin Seiki AS68RC w/ Torque Converter (650HP)

Next Gen Diesel

Introduction:

     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 AS69RC transmission.

Note: This is a complete transmission, not a rebuild kit. If you would like to build this transmission at home yourself, or have a transmission shop that you’d like to have build your transmission, you can use our rebuild kit version of this transmission.

Our 10-Step Transmission Remanufacturing Process:

  1. The first step in our remanufacturing process is a complete and total disassembly and inspection of all internal components, including the torque converter, geartrain, hydraulics, clutches and/or electronics.
  2. All wear components, such as bushings, bearings, washers, gaskets, seals, O-Rings, clutches, steels and more, are thrown away regardless of their health or usability, even if brand new.
  3. An intense cleaning session using the highest quality cleaning agents available to modern manufacturing ensues, steam tanking and hand cleaning these parts for up to 8 hours.
  4. We begin our inspection of the few remaining core hard parts to ensure that they are 100% re-usable, unworn and undamaged. Should a core part (such as a case) be irreparably deficient or unusable, it is properly discarded and replaced with a brand new one.
  5. At this point, the assembly process begins. All components consistent with your build sheet are staged and the proper machining, assembly and calibration of the product begins.
  6. Upon completion of all assembly, applicable components are individually tested on their respective machinery to ensure proper function and integrity, specifically hydraulics and electronics.
  7. At this point, final assembly begins. All pre-assembled internal components are then completed within the case, tested and forwarded to quality assurance.
  8. Prior to leaving our facility, a separate team member then inspects the final product, ensuring that the product matched the build sheet, and finishing touches like sensors or pan bolts are retorqued to assure future success for our product.
  9. At this point, the completed transmission is crated, the logistics of delivering your product are coordinated, and the item will proceed to shipping to prepare for embark to it’s new home.
  10. Upon completion of the 9 previous steps, you will receive notification of the product’s completion, passage of our quality control measures, and tracking information once applicable!
