Chevrolet: electrical, dead battery, starter motor

Question
I am trying to narrow down an electical problem.  I just got my car back from a new tranny install.  when i picked it up it started no prob.  after the car ran and drove for 1/2 hour i shut it off and tried to restart it and had no luck.  when i turn the ignition the starter does not engage.  No clicking, no response at all.  I have a new battery and i a wondering if this is a solenoid issue or something else.
thank you ryan.

Answer
HI
 Ryan, If you just had it fixed, I would turn around and take it right back to the place that did it. I would first check the battery and term. to be sure it is good and has a charge.  Than the starter motor , solenoid and wires, but if you  just got it back from the tranny shop, take it right back as they could have done something. ok let them fix it and you should not have to pay if thay did it.
and it might just have a dead battery .
