My 09 has it, and all of the other C-series gearboxes I've torn apart use what appears to be the same part. Looking at the compatibility of the speedo sensor (83181-12020) it's used on lots of stuff: "TOYOTA: 14 models, 905 variants between 1991 and 2013."

The speedo hole was there on the 2012, just capped off, but I don't recall the plastic speedo driven gear being on the diff carrier.
