Went by our local car show today in Cottage Grove, WI. Lots of beautiful cars and wonderful people out there. We had a great time getting to know some of these people and we had a few inquiries about adapters!

Here is just some of the cars that stuck out for me personally. I might have a thing for old Fords...

7.3PS/IDI Update!!!!

We’re officially starting to assemble hardware kits now that we’ve completed our Revision 4 production parts! 🎉

What does this mean?!

You’re going to start seeing tracking notifications on your orders! We’re beginning with the kits that did not initially order the US Shift standalone controller.

Our first shipment of controllers is expected to start arriving next week. As they come in, we’ll begin shipping those kits in the order the controller orders were received.

We are incredibly happy with the fit, function, and overall design of these parts. Getting everything to this point has been a LOT of work—not to mention the many, many late nights that the team at Baumann Electronic Controls/USShift.com has put into developing and refining the controller.

The countless hours of phone calls, texts, testing, and design work are finally coming together, and we’re extremely excited to start getting these kits into your hands.

We know this has taken a little longer than we originally hoped. Unfortunately, some things are simply outside of our control. We’re still waiting on some of the input shafts from our gear-cutting shop. These are complicated parts that require heat treating and surface finishing, so the process takes time.

We truly appreciate everyone’s patience and understanding while we’ve worked through the production process. We’re getting very close, and we’re excited to finally start shipping! 🇺🇸🔥

Thank you for sticking with us!

Well here is the video you have all been asking for!!! This is driving video of the 7.3 Power Stroke with the 10R140. There's regular driving and even a boost launch. The truck is a freight train and you don't see any lag as it pulls hard through the gears.
Karl and Chad discuss the tuning of the US Shift controller vs OEM 10 speed tuning and what makes having an Aftermarket controller so much more advantagous.

Well here's the video you have all been asking for! This is video of the 7.3 Power Stroke with the 10R140 swap installed. It is crazy seeing how this truck just pulls and pulls. Karl and Chad discuss some of the issues with the OEM tuning and how the US Shift Controller eliminates this and you can get that positive engagement.
There are a couple of boost launches, pulls and downshift pulls. This will hopefully answer most of the questions out there about drivability.

Here is a little 7.3 PS/IDI to 10R140 update for everyone. We have several parts finished or on their way from our vendor (starters). These shafts are 4140 Heat treated and Nitride coated. This gives the splines a very hard surface finish to take a abuse you guys are about to throw at it.

We also have the cooler line adapters back from Ano and laser, The transfer case adapters are also finised and waiting to get assembled & packed. Lots of progress is happening!!!!
