The TCU on my 2015 was beneath the steering column. It’s not mentioned at all in the widely circulated 2014 version of the service manual. Someone sent me the attached section about that system.

I believe you have to remove the center console “rails” and passenger dash cover to access some of the bolts between the steering column and center console. There’s also a few panels under the wheel and on the Driver’s side (door facing) that need to be pulled. I didn’t remove it fully but was able to access enough to get my hand in and confirm feeling the battery compartment hump.
