The 46-47-48 series doge autos are not a junk design.
They were poorly assembled and set up with much too low pressures.
Get the clearances right and pressures right and they hold a lot of torque.
The faster chevy duramaxes are using this trans instead of the allison!!! The Cummins does not hurt them if set up right.
They are a basic 727 auto from the 60's with OD on it.



Hmm... I need to get my hands on this info on modification. Does the same apply to newer 45 and 545 rfe transmissions? A friends ram 2006 that is, transmission gave out at 60,000 miles
