The Quick 4 is a powerful, fully-featured, easy-to-use, stand-alone transmission control system. It enables the use of modern, electronic four-speed transmissions on a wide variety of vehicles that lack OEM capabilities, such as classic cars, trucks, or motorhomes. 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 the shift points, firmness, torque converter engagement, and much more. The Quick 4 stand-alone transmission control system does not require the use of a laptop for tuning. Tuning can be done through the user interface with a soft touch dial and LCD screen. There is free downloadable tuning software to fine-tune your transmission with a Windows-based PC.
