I owned a 2013 Ford Focus as well. In the nine months of ownership, the transmission was replaced twice. Every transmission worked fairly well and then after about a month would start to stutter on acceleration and acceleration would lag then accelerate quickly startling me.

I was so glad to get rid of that car.

Cannot say if it is exactly the same issue, but it seems that the Ford mechanics (at least here) are not trained to repair them and are not even capable of finding what the actual "root" issue is.

Additionally it seems that Ford has not found a good procedure to revive the transmission (i.e. new or rehauled transmission fail the same way).

A number of out-of-warranty cars (not that having Ford do anything effective within the warranty period is in any way easy) here in Italy (Focus and S-Max) have been seemingly recovered by using a special procedure to wash/clean the transmission of the old fluid, put in new "special" one + additives (and replace the filter) , then there is the need (via ODB2) to reset/calibrate the gearbox electronics.

The same or similar issue affects/affected also the DSG-7 gearbox mounted on many VW's/small Audi's (and Sjoda's/Seat's).
