Will a truck or CTS V 6l90 work in an SS?

I'd hate to jump into a project like that and find out after a bunch of work and money that it won't work for some oddball reason though.

Might want to ask on HP Tuner forum to see if the Trans TCM and the ECM are compatible. It can get pretty detailed on OS numbers and Service numbers on what will match.

Wouldn't I be able to swap out the TCM from my 6l80 to the 6l90?

I don't know.

I did the 6L80 to 6L90 swap a few years ago on mine.
I used the same computer and harness.same crossmember.
After I installed it,I had it towed to the local GM dealership and just ask GM to reflash the TCM to a ZL1 Camaro which I provided a Vin number.And I drove it back home.
The 6L90 that I used was a ZL1,and I also have a spare. I know a few used the CTS-V tranny too. But I haven't heard anybody use a truck one yet.

A 6l90e from a 2wd truck or van will fit in a camaro after changing the rear output shaft with driveshaft flange and rear extension housing. I just installed a new take out 6l90e from a van after changing those parts. Complete trans disassembly is required to change them though.
