RAM had it made with Cummins, but transmissions were iffy till they offered the Aisin. Meanwhile Them D/A's Kep' Rollin' On.
Actually not exactly. RAM started offering the 68rfe behind the 6.7 way before the Aisin and it has proven to be a great trouble free transmission lasting for hundreds of thousands of miles.
I mentioned the RAM transmission because of remarks by a professional transmission builder on another forum:
"...this transmission has a big issue with the input drum stripping out in the drum... have experienced many stripped out drums in the diesel... just too much torque for the steel shaft and aluminum drum..."
As always, Your Mileage May Vary...
