The tech stated "had trouble communicating with control module AND with several control modules. I have seen the TCMs be very intermittent, but when they start acting up, all sorts of things will shut down due to data line not communicating between modules. I know this was shot down in the prior thread that was closed, but it happens.
Is the thermostat code gone is what I would want to know and, yes what about that 02 code?
