It has been long rumored that the 2018 Mustang refresh would usher in a new automatic transmission that Ford Motor Company has co-developed with General Motors, as we reported last year.

We now have our first unofficial confirmation of the 10-speed automatic transmission (10R80) which will be offered for the 2018 Mustang.

The new 10R80 transmission just appeared under the Transmission selection menu for the S550 Mustang in Microcat, the online database system used by Ford dealerships to look up parts for its vehicles.

While the part is not directly linked to any specific model year, and since the 2018 model year is not yet selectable within the system (showing up only as “2015+ Mustang” currently), this provides the first solid indication that the new 10 speed auto is coming soon and is all but assured for the 2018 Mustang.

Exciting times are ahead as the next model year S550 Mustang will debut new transmissions along with various engine, cosmetic and feature upgrades.
