New GM HD "Allison" trans not built by Allison

GM is or at least was building the allison 1000 in house even after the sale of the allison division in 2007.

and the 6.6 was a joint design headed by Izusu, and GM builds them in house.

GM owned Allison until 2007.

Turns out GM is actually the ones building the new "Allison" 10 speed transmission that is going in the next gen HD trucks. They are keeping the brand name Allison but it won't be made by Allison Transmission Corp. Allison does say they will "verify" the transmission though.

Interesting way of looking at it.

That actually happens a lot with other makes as well. Ford had ZF design many of their 6R transmissions, but were built at Ford facilities using many ZF parts. Ram did the same with their 8 speed, but also sold variants built by ZF as well as those built in house. Hence the reason why there were two 8 speed models in their 1500s and other vehicles that used these transmissions. The ones built by ZF are 8HP70 and the one built in house are 870RE.
