Message: <blockquote data-quote="SLE" data-source="post: 378173" data-attributes="member: 3889">The Allison moniker goes with the 10L100 heavy duty's or also known as the Allison 1000 and was introduced in 2020.You can call it what ever you want if it helps you sell more, but GM brought back the hydra-matic moniker for the 10LXX series of transmissions starting I believe back in 2017.  The new hydra-matic series includes the 10L80, 10L90.Here's an article right from GMs web site talking about it in the 2017 Camaro.<a href="https://news.gm.com/newsroom.detail.html/Pages/news/us/en/2016/may/0511-10speed-gm.html" target="_blank">https://news.gm.com/newsroom.detail.html/Pages/news/us/en/2016/may/0511-10speed-gm.html</a>Might want to brush up on your transmission knowledge..............Funny thing is the development of the 10 speed transmission was a joint venture with Ford Motor Co. Ford was charged with the design of the longitudinal mounted 10-speed found in rear drive vehicles and GM was in charge of the design of a transverse mounted 9 speed for FWD based vehicles. GM and Ford both use the 10 speed that Ford designed however GM is the only one using the 9 speed and Ford elected not to use that and instead developed there own 8 speed transverse mounted transmission as they didn't find sufficient efficiency gains with the 9 cog box to offset the added complexity and weight.sorry, way off in left field derailing from the baby Duramax discussion.........Carry on</blockquote>
