Even the 4R100's have a very strong track record in work trucks.
After further research, I'd tend to agree with you. I think the failed trannys I had been reading about were all due to modded trucks. I have read that if you add even the simplest mod to the 4R100 when tuning a 7.3 it will really make a difference in longevity.
BTW, I went out and bought a 7.3 F350 Crew Cab because my daughter is too tall for the back seat in the Dodge Ram. Now I have to sell that V10 Ram. But I got a good deal on it so I'll be able get more for it than I paid. Ironically, the Dodge 2500 V10 gassser has more towing capacity than my F350 7.3 diesel dually. I would've never thought that to be the case. I really like that V10. It is super durable. But I have no use for two trucks so it will have to go. I'm getting the same fuel economy in the gasser as the diesel when it comes to towing. Haha.
