2001-2016 AlliLocker - Allison Torque Converter Controller
Fits 2001-2015 Allison Equipped GM Trucks
Control your torque converter from the palm of your hand with the AlliLocker from Fleece Performance Engineering.
The AlliLocker is 100 percent code free when used on the track 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 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.
WARNING: This product is intended for closed course race use only. Do Not use on public roadways.
