Mine are 1/2 in. square drive. The plugs are 3/4 pipe, most likely 1/2 or 5/8 allen.

1/2 inch. A 1/2 inch ratchet works great.

Note the hex tranny drain plug at the extreme bottom of the attached picture, partially obscured by the "06" of the date stamp and the SS watermark.
Not true. Most of the axles, T-case and trannys use drain plugs with a 1/2" square recess and can be removed/replaced with a 1/2" ratchet or breaker bar. However, the English built trannys use a different drain plug which requires a hex allen wrench to service. It is possible, though I have never heard it mentioned, that some of the other components used the hex drain plug, either by design or mixup during field servicing.westfolk said:

Every small tool box should have the two aforementioned items as standard equipment if you have any inclination at all of working on large trucks...Of course you checked all the fluid levels before you drove the said truck home from the DRMO or after it was delivered to your home base and before driving or starting... A piece of hardened 1/2 bar stock was part of the biil with most small equipment in the Korean war era so you could use the issue adjustable aka crescent wrench to remove the plugs.

I have been known to use a pipe wrench on the OD of the plug where a bit of it (sometimes)extends from the hole in an emergency...

For the 9/16" hex drive plug, Vice-grips clamped on the threaded section of a 3/8" bolt will work(use the hex head of the bolt in the plug)(or double nut the bolt). Or for less than the cost of a good 9/16" allen wrench, buy a 3/8" all-thread rod coupler and use it with a wrench or socket .Or just face the fact that BIG trucks need BIG tools and buy some.(takes very little to justify having more tools in my book).
