EconoMax™ 68RFE Rebuild Kit w/ Torque Converter (550HP)

Next Gen Drivetrain, Inc.


     Back by popular demand is our “SuperStock” series of our 68RFE transmission lineup. The 68RFE is easily one of the most problematic and untrustworthy transmissions that currently plagues the diesel truck world. It is a promising source of overdrive failure, broken input shafts and crossleaking valve bodies to say the very least. We even did a full-length technical publication on the 68RFE, it’s problems and it’s solutions. You can read more here:

>>> Transmissions 101: 68RFE Transmission • Problems & Solutions

     Fortunately, we have gone back to the drawing board in the interest of creating a product that was affordable and practical while maintaining all of the necessary updates and improvements to live the longest life possible; a "once and done" transmission. The result was our incredibly long-lasting and crisp-shifting EconoMax™ 68RFE Transmission.

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 EconoMax™ 68RFE Transmission here:

This unit is best for:

  • Daily Driving
  • Towing/Hot-Shotting
  • Stock to Light Power Increases
  • Long-Lasting Clutch Materials
  • 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.
