What is "1" on the dashboard next to gear indicator?
On a new 2013 Silverado 2500HD 6.0 engine, next to the gear selection box on the right side close to "M" there is a "1". This 1 is not an indactor for what gear you have chosen in manual mode. The manual mode gear indcator is between the M and the mysterious "1". The salesman nor the Service manager knows what it means.
