SafeLock® - Clutch Protection Technology

Exclusive to MM4X4 lockup kits is SafeLock® which prevents excessive wear that occurs 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. 

It will also immedately unlock the torque converter under emergency braking conditions.  This helps avoid mechanical shock to the driveline and transmission caused by an impact, and avoids any possible interferance with safety systems like ABS and Stability Control.

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