My understanding of the gm truck hybrid transmissions is they are 4 speed transmission with electric motors at the input/output. The term "cvt" is a bit misleading imo, there is no slipping component as in Nissan CVT's.

And yes, I did back it up a moderate hill into our garage. No clutch slippage, all movement in reverse is powered by the output electric motor if I understand correctly.
"Although the transmission mechanically has only four conventional gear ratios, the electric motors allow it to function as a continuously variable transmission. This variable ratio functions in addition to the torque multiplication of the planetary gears."
