'dT' is the Tolerance Diameter in mm.

From page 8 of the AGMA 2015-1-A01 standard:

"The diameter located one normal module below the design outside diameter, thereby being approximately at mid-height."

dT = Do - 2mn

Do = design outside diameter, mm.
mn = normal module, mm.

AGMA released a calculator to use free of charge.
It looks like it's no longer available on their site.
I'll see if I kept a copy.
