Quick 4 Transmission Controller

The US Shift Quick 4 Gen2 is a powerful, fully-featured, and easy-to-use transmission controller built on REVolution architecture. This controller enables the use of modern, electronic four-speed transmissions in a wide variety of vehicles, including classic cars, trucks, or motorhomes that lack OEM capability. It can also be used to enhance a modern vehicle's performance by taking over control from the OEM computer, allowing the user to directly adjust shift points, firmness, torque converter engagement, and much more. The Gen2 Quick 4 boasts a redesigned PCB with improved functionality, ease of use, power efficiency, and diagnostic abilities. It features a new OLED user interface display that is bright and legible in daylight, with excellent contrast and a wide viewing angle. The display also has a wider temperature range for reliable operation in extreme conditions. The user interface provides real-time information and allows for most adjustments, such as shift timing, firmness, and torque converter clutch engagement, to be made directly from the unit without a PC. Diagnostic tools are comprehensive, with precisely monitored solenoid outputs and more specific error messages to pinpoint problems. Advanced diagnostics data can be accessed through the UI's menu. The redesigned circuit board is more power-efficient and runs cooler, with added protection circuitry to prevent damage from miss-wiring. It also features a robust, high-temperature-rated EEPROM IC with error correction for storing critical data, rated for at least 200 years of data integrity. The Quick 4 retains advanced algorithms for optimal shift control and synchronization, precise torque converter clutch control, AccuShift learning capability, and full line pressure control for each shift. Additional features include adjustable throttle lift delay, burnout mode, up to 4 pre-loaded shift calibrations, FLEX-SHIFT shifter re-mapping, transmission slip detection, 100Hz high-resolution data logging, and dedicated 4WD options. Its compact size (4.165 x 2.8 x 1.1 inches) allows for installation in tight areas. The Quick 4 is compatible with GM 4L60E, 4L65E, 4L70E, 4L80E, 4L85E and Ford AOD-E, 4R70W, 4R75, E4OD, and 4R100 transmissions.
