Allison was the name of an engine manufacturer that made a
wide range of engines. IRC its now a subsidiary of RollsRoyce

There is an Allison transmission division of GM that still makes
[very good I understand] truck transmissions.

Allison manufactures heavy-duty automatic transmissions (for lazy,
limpwristed city bus drivers). Rockwell dominates the market for long
haul, over-the-road truck transmissions that requires manual shifting.

Is this a different Allison than the WWII engine maker?

It's the same company. Allison (and Rockwell) are heavily involved
in the aviation industry.
