2001-2016 Duramax Fleece Performance AlliLocker Torque Converter Controller:
Fits 2001-2016 Allison Transmission Equipped GM Trucks.
Control your torque converter from the palm of your hand with the AlliLocker from Fleece Performance Engineering.
The AlliLocker will allow you to bypass the TCM controls 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 is intended for track use only and is NOT designed to be used on public roadways. If used on public roadways, the AlliLocker may set a DTC causing a range shift inhibit. This can typically be cleared by a key cycle. When used on the sled pull or drag race track, where there is only one lock event, the AlliLocker will not cause a range shift inhibit.
Operation explained in plain English:
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.
WARNING: This product is intended for closed course race use only. Do NOT use on public roadways.
WARNING: Always disengage the bypass switch and unlatch the lock switch when not in use.
