The Fleece FPE-ALILKR AlliLocker Torque Converter Lockup Controller is a game-changer for GM truck owners with Allison Transmission between 2001-2016. Take full control of your torque converter like never before with this innovative device from Fleece Performance Engineering.

Designed for track use, the AlliLocker puts the power in your hands to bypass TCM controls and lock or unlock the torque converter on demand. Simply switch off the bypass to let the TCM take over the torque converter clutch again. Whether you're hitting the sled pull or drag racetrack, the AlliLocker ensures a seamless and efficient lock event without causing a range shift inhibit.

Operating the AlliLocker is straightforward. In normal mode, let it be until you're ready to take charge of the TCC. Engage bypass mode for complete control with the latching pushbutton. Press it down to lock the TCC, and press it again to unlock. Always remember, this product is exclusively for closed-course race use and should never be used on public roads.
