2015 Chevy 2500HD 6.0L gas Ike Gauntlet

The driver didn't like the fact the trannie didn't shift down fast enough. On our 2001 8.1 would down shift very quickly. A little faster than I liked but it wasn't a big deal. Our 05 duramax wants to hold a gear longer than I want it to so it is an easy fix to hit the D button and go down the 4th and not lose any speed. Holding the throttle to the floor is for testing only. RV'rs are smart enough to drive smart most of the time .
