Hi,

If you open the hood, it is located on the driver's side of the strut tower. I attached two pics below. The first pic shows the location of the TCM and its mount. Picture two include the directions for replacement.

If you plan to replace the module, it will need to be programmed to your vehicle.

Let me know if this helps.

I saw this picture earlier. That's not where it's at.

If it isn't there, there may have been a different transmission used. If that is the case, the transmission is controlled by the powertrain control module (PCM/ECM) which is located in the air cleaner housing. See pic 1 below.

Also, pics 2 and 3 are the wiring schematics.

Let me know if this helps.
