1993 12 valve.. what tranny?
 

i have just the motor and t case, it had an auto. what will it bolt to? 727 out of a gas dodge ? i need to find something to use? help ! i dont care about over drive etc, just need to find out what will bolt to the motor.

any 727 will if you have the cummins to 727 bellhousing adapter thing that they used from the factory.

But you want it built for the diesel rating not just a gasser. It was originally a 518, a modified 727.
