Ordered a new TCM, which I gave them my VIN to program. I received it and went to install it but couldn't find the location of TCM. Check in air housing unit only thing there was the PCM, ECM, and the ECU. One unit with 3 different plugs. So, the TCM that I ordered is only one unit and can't find its location or did they send me the wrong TCM?

Good morning,

I attached the procedure for replacing it for you.

You also must have it programmed to your VIN with a factory scan tool.

The black connector is the only connector for the module. Make sure the number on your replacement is exact with the old unit.
