Description
Product Overview
The US Shift Quick4 Gen 2 is a fully programmable 4L60E standalone controller designed for GM 4L60E, 4L65E, and 4L70E electronic automatic transmissions. It manages shift timing, shift quality, and torque converter lockup when factory transmission controls are not being used.
It allows you to run an electronically controlled GM overdrive transmission without relying on a factory PCM or OEM computer. Common applications include LS swaps, classic trucks, hot rods, muscle cars, and custom builds using a Gearstar 4L60E-family transmission. The Quick4 provides the electronic control needed to manage your transmission and serves as a complete 4L60E standalone controller for custom vehicle applications.

Faq
A 4L60E transmission controller manages key transmission functions, including shift timing, shift firmness, and torque converter lockup. It provides the electronic control required for proper transmission operation when factory controls are not being used.
A 4L60E transmission controller receives information from vehicle sensors and uses that data to control transmission behavior. It determines when the transmission shifts gears, how firm those shifts feel, and when the torque converter engages or locks up.
Yes. The GM 4L60E is an electronically controlled automatic transmission that requires a computer or transmission controller to operate correctly. Without electronic control, the transmission cannot properly manage gear changes or torque converter lockup.
An aftermarket controller provides transmission control in applications where a factory PCM is unavailable or no longer practical. It also allows users to adjust shift points, shift firmness, and torque converter lockup settings to match their vehicle and driving preferences.
A factory controller is integrated into the vehicle's original engine and transmission management system. A standalone controller operates independently of factory electronics, making it ideal for transmission swaps, custom builds, classic vehicles, hot rods, and LS swap projects.
