Product Information

The Fleece FPE-ALILKR AlliLocker Torque Converter Lockup Controller for your 2001-2015 GM Duramax allows complete control of your torque converter from the palm of your hand. The Fleece Performance AlliLocker 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. See operation guide below:

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.

  • Easy Operation
  • Controls Torque Converter

Note: AlliLocker is not intended for street use! Competition and Off-road use only! The Module does exactly what its told, when its told without codes every time it's used down the track, but should be powered off between each forced lock or un-lock event. Multiple uses under a single key cycle will activate Allison Diagnostic Reasoning Codes.
