On most TR4 overdrives the plug is castellated.  The proper tool is a
tubular wrench with teeth to fit into the castellations.  One could bee
fabricated fairly easily if you can find a piece of pipe or thick-walled
tubing od the correct diameter.
 
An easier solution is to tap the plug off with a brass or copper drift.
Tap gently so as not to damage the plug.

Mine really clunks hard if I engage it without using the clutch, so I
normally use the clutch.  It disengages smoothly without the clutch.

If cars had evolved as fast as computers have, by now they'd cost a
quarter, run for a year on a half-gallon of gas, and explode once a day.
