2007 ram 3500 5.9 Cummins. Driving home everything fine all of sudden just cut off check engine light flashing and won’t even turn over. Also no gear numbers lighting up. Just had transmission put in a week ago but everything has been running fine?

I am not really that familiar with the automatic transmission operation on a 2007 truck, but I would recheck every electrical connection related to the recent transmission work that you had done.  It sounds like communication to the transmission has been lost.
