The only thing bad I have to say about the Ram HD's is that all of their automatics transmission (even the Aisin) are horrible in regards to being in the right gear at the right time compared to the Allison. I have not driven a stock L5P yet, but I have driven plenty stock LML's with the Allison and the shifting is almost telepathic compared to stock Ram transmissions. There is no need to manually upshift or downshift and is comparable to my custom tuned 68RFE in my Ram 2500.
The downside to the Dmax is that it does not feel as strong at lower revs compared to the Cummins. Being a long stroke engine, the Cummins has more naturally aspirated torque below 1,600 rpm and you have to to give the Dmax a little more rpm and boost to feel the same torque.
EDIT: Oh, and the Cummins could use a little more power, but that would require it to have a CP4 pump with more pressure and piezo injectors to meet emissions with that added power. I would rather have a reliable CP3 pump and electronic solenoid injectors while adding power afterwards. That is just me.
