( ps i didnt remove the plugs , I am waiting to try and use the correct allen socket. thanks

17 mm Allen Wrench
Use a small hammer and tap allen wrench end into the center of the drain plug.
If that does not work....you will have to use channel locks or small pipe wrench on outside of plug.
Actually.......
I would insert the 17 mm Allen by tapping and then place channel locks on outside using both wrenches.
The Trans Drain Plug is the same size and is usually scuffed from road rash.
You can use a larger box wrench over the end of the 17mm allen end as leverage along with the channel locks on outside of plug.
The transmission fill and drain Plug threads are M24 x 1.5 and
zfdoc should have them
When you install the plugs use a bit of Permatex Form A Gasket Sealant (or similar) and do not tighten plugs too much.
See Note D LT5/ZR-1 Fluids
REMOVE THE FILL PLUG FIRST
