You mean the big nut? I don't see a spec anywhere, but judging from how hard they are to remove, I'd guess at least 75 ft-lbs.

No it's not a nut but a bolt that is 3/8 or 7/16 fine thread with a thick washer thanks for the reply

Do you have the drum brake on the trans?

You can always look up torque values for bolts/nuts by googling "bolt torque chart" It is determined by hardness, thread pitch and bolt size. ie grade 8 fine thread is different then grade 5 fine thread.
