emailed previously, and the data is available in the docket as part of
the NODA.)

ISX 450 and 400 ratings were tested with TC10 and USP transmissions on
grade profiles from NPRM and new profile D.

Running on profile D shows expected trend of increasing FE benefit with
lower axle ratio, though different absolute improvement levels compared
to NPRM grade profile.
