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

Next Gen Drivetrain, Inc.


     Back by popular demand is our EconoMax® 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:

Why Choose an EconoMax® Series Transmission?

     EconoMax® Series transmissions are designed to rival the cost of an OEM replacement, but far more reliable, featuring all essentials necessary to withstand the test of time for factory power or lightly modified applications. These transmissions generally feature upgraded pumps, valve bodies, torque converters and friction materials whilst also consisting of a complete and total remanufacturing in excess of all OEM specifications.

     EconoMax® Series transmissions shift smoothly, operate at comfortably low temperatures and are designed to optimize for longevity, low cost of lifetime maintenance and direct OEM compatibility. Further, they're highly affordable given their robust credentials.

Their blend of concise shifts, low cost of maintenance and tremendous reliability make them an attractive option for the majority of people looking for an entry level transmission with top shelf reliability.

     If that isn’t attractive enough, these transmissions feature a 2 year, unlimited mile warranty. We design these units to ensure that clients looking for an affordable and reliable alternative to OEM parts have access to a tremendous option.

     Next Gen Drivetrain, Inc. is a Veteran Owned and Operated company in gorgeous San Diego, California that specializes in engineering, developing and manufacturing the height of automotive transmission technology.

We are an engineering and manufacturing firm specializing in automotive transmission technology, ranging from exotic imports to muscle cars to diesel trucks.

     We’ve invented dozens and dozens of different unique transmission parts from nothing that are exclusive to Next Gen Drivetrain™, not to mention developing over 100 different custom transmission and torque converter build sheets.

Next Gen Drivetrain™ parts are proprietarily engineered in-house and manufactured right here in San Diego, California.

     Further, everything we develop is designed to be the highest quality and best functioning component first, with all other metrics secondary.

When purchasing a Next Gen Drivetrain™, you can be assured that you’ve chosen the most premium option available, far more than some basic updates and a colorful painted exterior.

     We highly encourage you to compare our build sheets to any similarly priced product by a so-called “competitors” as you will see Next Gen Drivetrain™ products have no true equivalent, featuring the most extensive set of deliverables at their respective costs.

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, this is no more.
