2014 RAM Diesel 1500

I agree the 1994-2001 transmissions weren't up to all that torque at 1800 RPM, But I have never had a transmission go out or cause any trouble in any of them. I used them properly, though. Most city guys would tow in overdrive(bad), and not service regularly. I tow up to 15,000LBS on a regular basis, and the 07' up transmissions with auto tow haul are superb. In the 90's Ford Guys would spread the rumors of trans problems in an effort to disparage the Cummins. In reality the Cummins put it's max torque up to a thousand rpm's lower than the Ford or Duramax, so the ability of the engine to perform at such a low rpm challenges the best transmissions. The additional feature is a person doesn't have to remove the whole cab to service the engine, like Ford. Now, when the trucks get to the nine speed range, like the Semi trucks,
it will Improve mileage and longevity even more.
