The Allison name carries a lot of water. The name has a reputation for durability and has been used in connection with the Duramax name since 2001.

The transmission isn’t closely related to the 10-speed automatic found in the 2019 Silverado 1500, as far as we can tell, with General Motors describing the Allison-branded unit as “all-new.”
Silverado HDs Allison isn't really an Allison
OMG!!!
