When my trachee goes from fine to coughing green, bloody secretions in 27 hours, should I think virus or other pneum? Temp 101.8, ls congested. 

Think infection. Seek medical attention right away!
Consider infection. You are correct to be concerned about an infectious process (tracheitis, for example) in this scenario. Most commonly, a virus or bacteria causes (or sometimes we see both together) infection in the upper or lower respiratory tract, although other causes of infection are also possible. The patient should be evaluated by a physician to determine the most appropriate course of action.
