Hi,

On this vehicle, there isn't a separate transmission control module (TCM). In its place is the powertrain control module which controls the transmission.

The powertrain control module (PCM) is located under the hood next to the battery. If you look below, I attached a picture and highlighted the PCM.

Let me know if this helps or if you have other questions.

Take care,

Joe
