But the big difference is one will have a warranty and tranny that was designed for that power level, and the other has jepardized any engine/emission equipment/transmission warranty. That 68 tranny most certainly will not last very long.
My top Cummins ISB certified technician could not detect my module was on even with the latest Cummins Insite 8.1. Neither could the technician at the dealership when I went for an update. People keep saying that my warranty is voided, but even after four visits to the dealer(two oil changes, one for recalls, and another for an update and interior button replacement) I still have my warranty intact. They wouldn't have replaced the steering wheel button or update the trans ECM for free under warranty if I didn't have warranty.
I also have multiple friends who have 2010-2012 deleted Cummins(which I don't agree with deletes) running hotter more powerful tunes as a daily drivers than what I run without one transmission issue. The one with the DRW has over 180k miles which was mostly pulling a trailer for his hot shot service. You may say they won't last long based on whatever experience you may have with them, but from what I have seen with my own eyes I have no worries for my tranny.
I am not saying the 68RFE is bulletproof. No transmission truly is and all will burn up quicker than shnit if you drive them like a dumb ass all the time and without regular maintenance. I am just saying that I have seen many instances where the 68RFE had a long life even with engines putting out considerable more power than my truck is putting out with my Edge module and stock emissions equipment.
