The Story
Control your torque converter from the palm of your hand with the AlliLocker(tm) from Fleece Performance Engineering. The AlliLocker(tm) is 100% code free 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. 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.
