Hello,
There is no TCM on the car per say. It is integrated into the engines PCM which is normal for this car. But there is a ATM or TCM relay which powers the PCM side of the circuit Here is a wiring diagram (BELOW) so you can see for yourself. It seems like you might have a shift solenoid out. I would use the diagram and drop the pan to check the resistance of each one to see if one is way different from the rest telling you its bad and needs to be replaced. Please run some tests and get back to us so we can continue helping you. Here is the relay location under the hood with a guide to help you test it.

Good morning,
The transmission control is part of the engine control module. they are combined into one unit. Do you have any codes? if you do, list them so I can help you narrow the area of failure. Why do you believe the module is defective? This guide can help
