Hello and welcome to JustAnswer!

P0720 just sets in the engine controller when there is a code stored in the trans controller. The P0600 is what is set in the TCM. This is for a communication issue and could be several things.

Do you know the exact wording that displayed along with the P0600?

Does the speedometer work?

Exactly what warning lights are coming on?

Speedometer does not work, trans lights is on as well as engine warning, transmission , abs, I don't know the wording displayed behind po600.What's the does the break switch have to do with it.
The car at a mechanic that is not a Chrysler Crossfire expert.

The brake switch is irrelevant.

Does the ABS module communicate with a scan tool?
