Do you have the Aisan transmission? I've heard that they are having trouble tuning the Aisan trucks because it is on its own controller. I've heard it shifts funny with power added?
Here is possibly a major reason the GM Duramax and Allison does so well.
The Allison was designed with the Duramax and the controllers talk to each other. Also the GM engineers probably found with the Duramax and Allison combination the 3.73 gear gave the best performance for a wide variety of towing conditions including the Ike Gauntlet.
I did a spreadsheet comparison with a 4.1 vs 3.73 for the Duramax and the 3.73 would give the best results at 40 and 50 mph.
At 60mph the choice would be the 4.1.
Are you implying that the engineers designed to the test?
