Boy, Alison sure takes a big jump from 1st to 2nd
The Ram Aisin and the 68RFE both have a larger jump from 1st to 2nd than the Alison.
Alison change is 1.7127
Aisin change is 1.875
68RFE is 1.765
Bottom line the Alison probably matches the Duramax HP curve better than the Ram transmissions match the Cummins HP curve.
