Description
Product Overview
The US Shift Quick4 Gen 2 is a fully programmable transmission controller designed for GM 4L80E and 4L85E electronic automatic transmissions. It provides the electronic control required to operate these transmissions without an OEM computer.
This standalone controller allows users to manage shift timing, shift firmness, and torque converter lockup through an integrated tuning interface. It is commonly used in transmission swaps, custom vehicle builds, and applications where factory transmission controls are not being retained.
