Our coach (1976) was born with a Cummins 555 and allison mt41 trans.
The 555 is impossible to get parts for so I am planning a heart transplant.
I have a 24 valve 5.9 cummins. That is slightly tuned up. I feel this is going to be a good power plant for the bus with a bump in hp/to over the 555.
I have a couple transmissions I am looking into. The mt41 is not going to handle the torque of the new engine.
I currently have a lead on an mt645cr. Any experts in here that can tell me if this would be a good trans for this swap?
