01-14 Duramax Fleece AlliLocker Converter Controller
Control your torque converter from the palm of your hand with the AlliLocker from Fleece Performance Engineering.
The AlliLocker is 100% code free and allows you to bypass the TCM to lock/unlock the torque converter on demand. Turn the bypass switch off, and the TCM regains control of the torque converter clutch.
The Allilocker operation is simple. Leave it in normal mode until you want control of the torque converter clutch (TCC). When you engage bypass mode (left rocker switch) the TCC is completely controlled by the pushbutton on the right (it is a latching pushbutton). If you press it down it locks the TCC and stays locked until you push it again which raises the switch back to the open/unlocked position.
