Fleece AlliLocker (FPE-ALILKR)
Control your torque converter from the palm of your hand with the Fleece FPE-ALILKR 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.
Fleece FPE-ALILKR AlliLocker Torque Converter Controller Features:
- Fits 2001-2016 GM Trucks equipped with Allison transmissions.
- Manual Torque Converter Control: Lock or unlock the torque converter with the push of a button, giving you total control from the driver’s seat.
- TCM Bypass: Allows you to bypass the Transmission Control Module (TCM) and control the torque converter manually. Switch off the bypass to return control to the TCM.
- Track Use Only: Designed for drag racing and sled pulling, not for public road use.
- Range Shift Inhibit Warning: Using the AlliLocker on public roads may trigger a range shift inhibit, which can be reset by turning the key off and back on.
- Safe for Track Events: When used in single-lock events, like at the track, the AlliLocker will not cause a range shift inhibit.
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.
