So who makes their 3.0 diesel and also who's 10 speed transmission is this GM or someone else like Allison?
The 3.0 was developed at the Turin R&D Center in Italy. This was one of the parts of Opel that GM kept when they sold off most of their European operations. The 10 speed is the same Ford-designed, GM-manufactured unit they started putting in the Camaro in 2017 and the Silverado in 2019. The variant used behind the 3.0L has a different torque converter from other installations, and includes a "centrifugal pendulum absorber" to dampen any vibration that you might otherwise feel at lower RPMs.

I think it's pretty cool from a power and efficiency standpoint. I have my reservations about the rear-mounted timing chain, and belt-driven oil pump. Both sound like Audi-levels of maintenance nightmares when they get old.
