Hard to not be a hit. The same core architecture for the E-Series vans is how many decades old? Too bad GM hasn't done similar. And no, a re-brand of the Nissan van doesn't cut it Chevrolet.
All new powertrains for these vans forgoing the 4.6, 5.4 and 6.8 offered in the E-Series, with the Transit using the NA 3.7 V6, 3.5 EB, and the 3.2 Power Stroke I5 diesel. Only transmission is the six speed. That 10 speed would be nice in these.
