Fleece Performance Automatic Transmission Lock-Up Torque Converter Control
Fits 2001-2015 Allison Equipped GM Trucks
Control your torque converter from the palm of your hand with the AlliLockerT from Fleece Performance Engineering.
The AlliLockerT is 100% 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 desinged 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.
Products received may vary slightly from images due to manufacturing tolerances or supply chain variables.
