Dissassemble Your TT-01 Following the Reversal of Installation on Your TT-01 Manual

Open the Diff by undoing 3 Screws.

Inside You will find 3 Small Spinning Gears ( See Red Arrow)

Now Cram Blu-Tac, Playdough or Silly Putty into and Around the Planatary Gears till the Gears gaps in between the Gears are Covered. Dont worry if You Cover the Gears too much
Line up the Diff Cover and Re-assemble


DO NOT REMOVE THE GEARS!
They have to Remain Inside the Diff but they have to be Stopped Spinning and Cramming Blu-Tac, Playdough or Putty is the Safest way as If you dont like a Locked diff, All you have to do is Clean the Diff out of all the Putty and Re-assemble and Re-grease..

You Do this Mod at Your Own Risk.. No Damage or Responsibility will be Taken if you mess it up
