About Our Remanufactured ZF6 Transmission

If you’re looking for a ZF6 transmission for sale, whether that’s for a Ford ZF6 transmission swap, GM ZF6 transmission, or Chevy ZF6 transmission, we’ve got you covered!

We’ve been in the business of selling only high-quality used and remanufactured ZF6 transmissions to our customers, utilizing our team’s expertise on these models of transmissions to achieve the best rebuilds possible.

Why should you buy a used or remanufactured ZF6 transmission? One of the main reasons is cost and affordability, and the second reason is for fixing and patching up any problems that come with these transmissions from the factory.

Here’s how we achieve affordability & reliability:

  • Affordability: Buying a used or remanufactured transmission from us is a way to save significantly on costs compared to buying a brand new transmission. Even though we completely rebuilt the interior parts, we’re still using the same transmission body and core, allowing us to pass these savings onto you as a customer.

  • Fixing Factory Problems: The ZF6 transmission is much better at this than other models, but factory defects and issues still crop up every once in a while. Our expert transmission mechanics and engineers know what common problems the ZF6 tends to have, which allows us to fix these issues with ease. In our remanufacturing process, we either replace or re-machine every internal part of the ZF6, making sure everything is up to OEM standards. This lets you get an affordable, high-quality, long-lasting ZF6 transmission that’ll serve your vehicle for years to come!

By purchasing one of our ZF6 used or remanufactured transmissions with all known defects corrected, fixed, and eliminated, we’ll present you with a quality transmission that oftentimes performs even better than ones produced by the original manufacturer!

To keep our customers as happy as they can be, we also provide a 5-year warranty that covers unlimited miles for your remanufactured transmission.

And as another cherry on top, we’ll make sure you get free and fast shipping to any commercial address within the United States – the best of both worlds!

All in all, we’ve proudly served our customers for many years now, and intend to do the same with your ZF6 transmission. Whether you need a ZF6 swap, rebuild, or just want to order one of our used ZF6’s, we’ll make sure you get through the process quickly and painlessly without any headaches!

If you need a ZF6 transmission 7.3 liter, ZF 6-speed as they normally come, or just want to replace your ZF 6-speed manual transmission with a high-quality used or remanufactured one, our customer service team and expert staff will take care of you from start to finish.

ZF6 Frequently Asked Questions

ZF6 History & Information

The ZF S6-650 6-speed manual transmission is manufactured by the German car parts maker known as ZF Group or ZF Friedrichshafen AG. The ZF6 transmission is the immediate successor to the ZF5 manual transmission which it replaced in 1996. Designed for longitudinal engines, the ZF6 is rated up to 520 ft-lb of torque, making it an excellent choice for certain truck models.

The ZF6 was traditionally intended to be used as a heavy-duty manual transmission for vehicles such as diesel pickup trucks. Unlike most manual transmissions, the ZF6 utilized an external transmission cooler as well as an integrated oil pump for bearing protection and lubrication.

Over time, the ZF6 transmission tended to operate quietly, with smooth shifting, and positive gear engagement without any re-occurring issues or problems.

It was first introduced for 1999 vehicle models by Ford in their Super Duty trucks. General Motors (GM) also began using the ZF S6-650 in the year 2001 and made some modifications to their transmission’s design with slight differences from Ford’s ZF S6-650 version. The 6-speed ZF6 transmission was used in junction with a few different transfer cases including but not limited to the NV120, NV261XHD, NV271, and NV273F

Due to a decrease in consumer demand for manual transmissions in heavy-duty pick-ups and advancements in the technology accompanying automatic transmissions, Ford and GM stopped using the ZF6 transmission in their pick-up trucks in 2010.

Throughout its history, the ZF6 transmission was used in:

Since the ZF6 6-speed manual transmission could be used for either RWD or 4WD applications, it was used in both variations of truck models by Ford and GM.

Overall, the ZF S6-650 was an excellent heavy-duty transmission for consumer pickup trucks without any factory defects or known reoccurring issues, making it a great choice for Ford or GM trucks from the years 1999 up to 2010.

If you have a ZF6 transmission that needs rebuilding or need a transmission swap on one of your vehicles, we can help!
