If you’re contemplating a modern-day engine drivetrain swap into your classic car, truck or RV, listen up. A critical element of your swap is enabling your new electronically controlled transmission to interface with your engine’s ECM. Not to worry as US Shift Electronics has the perfect interface to connect all your 21st-century automotive electronics. Its Quick 4 product takes your engine’s TPS (Throttle Position Sensor,) and RPM data and sends it to your transmission instructing it when and how to shift.

US Shift fills us in on the details, “The Quick 4 is a powerful, fully-featured, and easy-to-use transmission controller based on our new REVolution architecture. It enables the use of modern, electronic four-speed transmissions on a wide range of vehicles that lack that 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 and torque converter engagement, and more.”

If all this piques your interest, stay tuned to Street Muscle.com  and LSXMag.com as we do a step-by-step install of a US Shift Quick4 in our 1996 Caprice project car. We’re going to hook up to a 4L60E transmission and we’ll show how to integrate and tune the Quick4 box so you’ll be up to speed when you install yours.
