Yes, all USA Sprinters have an automatic Transmission,
but wait, the T1N's had the 5G-Tronic/NAG-1 and needed to be downshifted
to 4th gear frequently when towing.
2007-2018 NCV3's with the 3.0 liter OM-642 V6 had the same 5G-Tronic/NAG-1
transmission and they 1 frequent manual downshifts in the RV's and when
towing, or with a really near full capacity load.
The 2014-2021 NCV3's with the OM-651 2.143 liter Inline 4 Cylinder had/have
the 7G-Tronic 7 speed and don't require and much manual downshifting, but
you can put them in any one of the 7 gears and it will stay until you manually select
another gear.
The C907/VS30 has the 7G-tronic 7 speed behind the OM-642 3.0 Liter V6 with the
paddle shifters so you can select any of the 7 forward speeds and the transmission will
stay in that gear until you change it up or down manually.
So, Sprinters give us nearly the best of the automatic transmission with the ability to
manually select whatever gear is appropriate like manual transmission.
I've had the 7G-Tronic in my 2014 and my 2019 and pretty much never used the manual
shifting capability as the 7G-Tronic takes care of all shifting "automatically".
That was not the case with the 4 earlier Sprinters with the 5G-Tronic/NAG-1
