It has been updated by Ford & the 12th pin has been removed.
This sends information to the Powertrain Control Module (PCM) that in turns sends control signals to the transmission.
If the engine computer gets bad info than it's extremely likely it's going to send bad control info to the transmission.
Luckily, it is not very expensive and a rather 'easy' replacement.
