Today I discuss all things automatic transmission lockup kits. I have recently fitted a Stockwell Extreme transmission lock up kit to my 2013 Toyota Landcruiser 200 series Sahara and it has made a massive difference!

If you have or are planning on modifying your auto 4WD, load your vehicle up to GVM, tow heavy loads or do all these things like me, than some sort of lockup kit has to be on your list of vehicle additions.

In this video I talk about what a lock up is and how it works, briefly explain the role of a torque convertor in an automatic transmission and finally dive into some statistics obtained from a side by side comparison.

Further, I specifically discuss the reasons that Toyota don’t fit these units to their vehicles from factory and why it’s important for 4WD’ers and heavy towers to seriously consider fitting one to their vehicle.

Stocklock extreme:
The EXTREME 3 Speed Stocklock is a new addition to the Stocklock family.
The new Stocklock “Extreme” transmission lock-up kit is a 3 Speed lock-up, and is much easier to operate as it is wired directly to the Sports shifter.
It has one button to turn the Stocklock on and off, and works the same way as the Dual Speed.
