This is the Xtreme Tow™ series of our Aisin Seiki AS66RC rebuild kit lineup. The Aisin Seiki AS66RC transmission has been both a blessing and a curse to the bleak Chrysler transmission lineup. It may be large and stout, but it is not without multiple common and easily preventable points of failure. Until recently, many of the Aisin’s OEM electronics have been inaccessible to the aftermarket.
At Next Gen Drivetrain™, we’ve asserted relationships with some of these companies directly to grant our customers unique access to all of the OEM Aisin Seiki electronics, ensuring a comprehensive and reliable new transmission. Despite this, in factory form it is a promising source of burnt K2 clutches, electronic failures and rounded out K2 hubs, to say the very least; all deep internal failures. Many of which can be seen 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 Xtreme Tow™ Aisin Seiki AS66RC 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 Xtreme Tow™ Aisin Seiki AS66RC Transmission here:

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.
