Allison&#8217;s new transmission is expected to be released in 2022, which is (around) when Ram will release their new class 2 and 3 heavy-duty lineup. Allison itself sells integrated hybrid-electric axles, but only for true heavy duty trucks (buses, big rigs, etc).<\/p>\n<p>An 8-speed ZF transmission is also being considered. FCA has had much success with ZF so far; and ZF is expected to release hybrid transmissions around the same time Allison releases their new 9-speed transmission.
