I'd crawl underneath and unplug the transmission harness. Fire it up and see if it still stalls out when you shift into gear.
It's either an electrical fault - stuck torque converter lockup relay, short in the harness, erroneous signal from the PCM - or it's a grenaded torque converter.
Unplugging the harness will eliminate all of the electrical faults. If it still does it, it's a mechanical problem.
You very well may get a check engine light for your troubles, but at least you'll be one step closer to figuring it out.
If it's electrical, pull the relay and verify that it is operating properly.
