Control Your Torque Converter

May 2014 Products

Thanks to the AlliLocker from Fleece Performance Engineering, Duramax/Allison owners from 2001 to 2014 can now control your torque converter from the palm of your hand. The AlliLocker is 100 percent code-free and allows you to bypass the TCM to lock and unlock the torque converter on demand. Turn the bypass switch off, and the TCM regains control of the torque converter clutch.

This product is intended for closed course race use only and is not to be used on public roadways and it’s important to always disengage the bypass switch and unlatch the lock switch when not in use. The AlliLocker retails for $179. (855-839-5040/
