This is the “All-In-One” series of our E40D transmission rebuild kit lineup. The E40D is a very old transmission platform based on the foundation of the Ford AOD dating back to the 1970’s. This means that the E40D is as old as it is outdated, and leaves much to be desired in terms of modern technologies that translate directly into longevity, performance or durability.
Fortunately, we have gone back to the drawing board in the interest of creating a product where the priorities of longevity, economy and practical use were all equal. The result was our responsive and versatile and easy to install "All-In-One" series rebuild kit for the E40D 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 longlasting and reliable SuperStock E40D Transmission here:
>>> SuperStock E40D w/ Torque Converter (550HP)
This unit is best for:
- Daily Driving
- Light Towing
- Stock Power
- Very High Longevity
- 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.
