Important News!


As part of our product line expansion plans, we are changing the name of our transmission control product line to "US Shift.com", effective immediately. Please note that the web site address for our transmission control products has changed to www.USshift.com, and that the old www.OptiShift.com address will soon become inactive.

This is only a product name change, so our company name, ownership, and phone number have not changed, nor has our main corporate web site at www.becontrols.com. Our current transmission control system has been renamed to "US Shift - Quick 1", making it the first product in the new US Shift product line. Please bookmark our new site, and watch for more products in the coming months that will be joining the Quick 1 to create the most complete transmission control product line available.

We are also excited to announce new, lower pricing for our US Shift - Quick 1 controllers. We have reduced the price of our flagship Quick 1 controller to $425. With this new pricing, you can get a Quick 1 controller with a complete wiring harness for as low as $565!

US Shift Manuals and Publications

We believe that the more you know about US Shift products, the more you will like them, so we encourage you to download and inspect our manuals and our tuning software before you buy our products. Please feel free to contact us with any questions that you may have.

Please note that these documents are provided in Adobe Acrobat (PDF) format, and you will need to install the free Adobe Reader or equivalent PDF viewing software in order to view them. If you are not sure, it is likely that you already have Acrobat installed, since it is widely used.
