Overview

Chevrolet Performance Connect and Cruise ZZ572/620 Engine and Transmission Packages

Chevrolet Performance engineers did all the hard work, designing and calibrating carefully matched Connect and Cruise powertrain systems for optimal compatibility and performance—while also identifying the complementing engine and transmission controllers, torque converters and supporting installation kits. The specially calibrated controllers are designed for retrofit installations in older vehicles, for easier and quicker installation—and, more importantly—operation without the need for third-party tuning.
