Allisonman, I have a 2000 Journey with 275HP Cummins and Allison MT643, 4 speed trans.
I have been told that the Cummins could be upgraded to 300HP but that the MT643 can't handle the increased power. Is this correct and can anything be done. I can live with what I have but a little more power would be nice in hills.
