We are opening up the Pre-orders on the first kits we have built.

  • Works with 6R80 transmission from a Modular V8 such as a 5.0 and 5.4 liter and be from a 2011 or newer vehicle for an aftermarket controller to work. The V6 transmissions will not work.
  • Will also work with 4R70W, 4R75W, 10R80, 5R110, 4R100, 6R140 (w/V8 gas case)
  • Utilizes an American built Powermaster high torque starter (included with kit)
  • Uses your stock Ford flexplate specific to your engine
  • Designed to work with the 4 stud converter found in most V8 style 6R80 transmissions. The 6 stud converter will not work.
  • CNC machined from 6061 billet aluminum (both adapter plate and converter spacer) At our shop in Wisconsin.
  • Starter can be replaced without removing the transmission and the kit doesn't require any cutting or grinding of ANY component. Bolts on easily with minimal tools

We offer package deals that include US Shift stand-alone controllers. If have a 6R80 we recommend the Quick 6 stand-alone. You will save $125.00 on your Speed Gems adaptor kit when bundled together. 

If you're planning on a Modular Ford AOD-E, 4R70W (wide ratio AOD-E), and 4R75? By adding a US Shift Quick 4 stand-alone transmission controller you will save $100 dollars off of the cost of your Speed Gems adapter kit. 

We have additional options from US Shift. Please give us a call or email us if you're not seeing what you need!
