Tightening the transmission tailshaft 30mm nut

I'm getting to the point where I'll be reinstalling the driveshaft on my 300SD. In tightening the tailshaft nut (long story why it was off in the first place), I tightened it to the point where the transmission was tipping over despite my best efforts to step on it. I think the torque wrench MAY have clicked, but I'm not sure. What do you guys think? Should I just bolt it up? It's very tight, bu I'm wondering what the "tight enough" threshold is.

The thing is on a splined shaft, so I can't imagine anything too horrendous happening if the nut does come loose. What do you guys think? I probably will put at most 5000 miles on this before I swap in a standard anyway...
