The US Shift Quick 4 represents the most intensive development project in Baumann Electronic Controls history, making the Quick 4 the industry standard in electronic transmission control. With all new exclusive features, its design is not evolutionary, but revolutionary.

  • The most advanced torque converter clutch control available, with several actions available during shifts.
  • Accushift ™ learning capability for the most accurate WOT shift points possible.
  • Full line pressure control for each individual shift, providing superior shift quality.
  • Adjustable throttle lift delay, overdrive shift delay, and ballistic throttle effect.
  • Burnout mode prevents upshifts while "pedaling" the throttle.
  • Up to 4 pre-loaded shift calibrations able to be selected on the fly.
  • FLEX-SHIFT ™ Shifter re-mapping capability.
  • Metric Support.
  • Transmission slip detection.
  • 100hz high-resolution data logging.
  • Dedicated 4wd options and features.
  • Compact size gives you the freedom to install in tight areas (4.165 x 2.8 x 1.1 inches)
  • And many more cutting-edge features

More transmission support will be available in the near future. Please contact us for more information

* 4R55E/4R44E transmission wiring harnesses do not include a solenoid connector, so you will need to splice the OEM connector onto the provided wiring harness.

These videos will walk you through the required steps to get started with our Windows-based tuning software. Our controllers come pre-loaded with an appropriate calibration for your vehicle and any required settings can be adjusted directly on the controller without the use of a computer. However, the PC-based tuning software will give you full access to all of the advanced features and allow you to change the transmission type, if needed.

I am using the Quick 4 with a BC 4R70W transmission and VB on my 4V JT Trim mustang. I am running mid 9s with it shifting the automatic valve body. I leave off the foot brake and just point the car down the track and let the Q4 do the shifting for me. It offers many configurations the stock EEC does not and is MUCH easier to program and tweek. The driveability on the street is great too. I highly recommend this product.
