The easy-to-use, graphical built-in tuning interface allows the most common settings to be changed without using a PC or laptop.

Our wiring harnesses are constructed from high-temperature, automotive-grade cross-linked polyethylene (GXL / TXL) wire and utilize the correct original equipment connectors for each transmission. The standard wiring harnesses are complete and require as few as three connections to produce an operating transmission.
The design of US Shift controllers and wiring harnesses are optimized to simplify installation and troubleshooting. Like our intuitive tuning software, our installation manuals are straightforward, well illustrated, and easy to follow.

Just recently purchased a Quick 6 for my 2008 Ford Expedition Roush Supercharged SUV. I updated to a 2014 6R80 from my original 6R75 and I gotta say this controller is the pinnacle of transmission controllers. The ability to fine tune your transmission is a must for any serious auto enthusiast. The software is top notch and the menu is easy to navigate, especially on the controller itself. The only real obstacle I had to overcome was going from a mechatronic 6R75 to a pcm controlled 6R80. My tuner Aric @Injected Engineering Kennesaw GA made everything happen from an updated calibration to making the truck able to run again without trans communication to the pcm.Read More...
I contacted US Shift to see if anything was in the works and they were in the middle of Quick 6 development. I stayed in regular contact with Jake, and one day the Quick 6 became a reality. I was offered a Beta Tester slot and I jumped at the opportunity. This turned out to be a great experience. There were a couple of hiccups at first, but Karl was right there to work through it. Once we got the initial settings worked out, I began adjusting the tune. This time, I was able to take full advantage of the Quick 6 software (no constant-pressure valve-body). It was very easy to navigate and any questions I had were immediately answered. I spent a lot of time perfecting the programming to my liking.Read More...
I wanted to thank you all for your amazing product. I purchased a Quick 4 for my built GM 4L80E in January of 2017. I finally finished my truck. The shifts are perfect. Could not ask for a better product. The use of a Laptop makes the shift points even better. Thanks again.Read More...
