bad converter?

[dusterbd13]

ive been working on a 68 hemi roadrunner all day, trying to finish the EZ EFI swap. it starts and idles great, but anytime you pull it into gear (automatic), it lurches and dies. the idle is set at 1000 RPM. it feels like when you are sitting at idle in a stick car and let out the clutch. just lurches and dies. if you start the car with it in gear, about the time it starts running, it starts moving. then dies out, like its being bogged down by being in gear.

after talking with FAST for a long time, and trying everything from relearning the computer to fooling the IAC, to having the idle set at 2000RPM, they said the car had a bad torque converter. does this sound right? is there any definate way to diagnose a bad converter without dropping the trans?

thanks
