SafeLock™ - Clutch Protection Technology

Exclusive to MM4X4 is SafeLock™ which prevents excessive wear which may occur when the torque converter clutch is engaged under high slip conditions.   


Using Advanced Digital Control, MM4x4 lockup kits read the real-time vehicle status from the ECUs to determine the amount of slip in the torque converter.  The clutch will only be engaged when within the same slip limit range used by the factory ECU, giving maximum longevity and reliability of the clutch. 

Only MM4X4 kits have SafeLock™, so why risk the long term reliability of your expensive transmission?
